Subject: Could "EMP Weapons" (elctro-magneticp pulse/beam weapons) of the Future, pose a threat to any "Techno-Dependant" Nation, resisting the efforts of progression to NWO's Global Dominace by enforcement plans of reducing them to a 3rd world nation overnight, via implementation, and deployment of these "EMP" weapons?

Please give this careful thought to those concerned, or NOT! because this just migh be comming soon, to a neighborhood near you! I mean when you really think about it folks, this would not even have been an option 30n yrs ago, or prior!

"Everything depends on the global computer grid now, including communications, transportation of passangers & goods, and right down wher it hurts the most... Banks & Power to run this great & wonderful Economy of ours.

EMP weapons have always been a threat, in fact many new designs take EMP into consideration and have a certain degree of protection. Use of a tactical EMP weapon against us would have grave results, however it is not what you should be worried about. There are many other weapons that have the potential to be devastating and are much easier to produce. The ones that scare me are RF weapons.

Gentlemen,

I have considered the idea & working mechanisms of the "Electromagnetic pulse weapon technology""//////..in past years.

Perhaps I am out of date and I respectfully ask you to give me any input regarding the subject.

Can you be more specific? My ideas of EMP are quite old & varied (intermixed with personal theories).

I do not now see the threat of lesser tech capable nations to "get a leg up", in regards to to EMP TECH.

The understanding of basic chain reaction nuclear technology seems to be the first hurdle for any science group, before they can hope to supply a country with EMP Technology.

Hi Howard,

I have only a laymans knowledge of what an EMP weapon is and what the theory of Op might be. This is mainly because I've never placed much thought in that direction. I do know about protection some circuits from EMP, and a little background on the history of that effort, and If you want to know about RF weapons and how they work, I can help you there too.

The State of Unclassified and Commercial Technology
Capable of Some Electronic Mind Control Effects

To help the reader appreciate the importance of this matter...
"We need a program of psychosurgery and political control of our society. The purpose is physical control of the mind. Everyone who deviates from the given norm can be surgically mutilated.

Please review the remainder of this article, at the link provided.

Increasingly, it is apparent to others that disabling computer networks, communications, and the general ability to cause mischief to an enemy is a desirable goal as it has always been in the past. China was in the news just a short while ago as being on record to develop a virus or other type of weapon for computer warfare to disrupt communications. I bring this into this thread, as EMP from nuclear blasts was a consideration when making sensitive things such as Air Force 1. Air Force 1 was thought to be a mobile command center for intransit communication when it was built. To be able to knock out the communication with the military while not actually killing the leaders of the country is a goal for an enemy. General warfare rules have agreed in the past that you don’t go after the leaders of the country you are warring with as it sets bad precedent. I think that the US ignored this when they bombed Libya. This sets a terrible standard as you can very easily set up a martyr which inspires the enemy to fight all that much harder.
However, wars have always brought change to technological level of science. To have that weapon, which the enemy has no defense for, such as the atomic bomb and Japan during WWII, can be a war ender. Hence a lifesaver. To use EMP as a weapon, if I understand this right, affects all electrical activity. If strong enough it is feasible that it could also end life within its blast range. Interfering with the electrical activity of the brain. So do we shield the soldier with some kind of new helmet? What of the civilians, as in the case of Iraq, where the military uses populace for a shield when erecting it’s defenses? Are the bleeding hearts ready to accept the death toll to the civilians as it was used as a propaganda tool for US consumption through CNN almost immediately after the bombing was done?
Yes, everything has computers involved nowadays. Critical areas of the military have already shielded their computers for just such an event. The civilians however have not. Such a weapon would cause havoc to the nation at large. It would take a few days/weeks to gather things up and get them back on schedule. Most of that cobbled up by replacing the computer with people. Everything from your food to money and medical help would be affected. Almost your whole apparent world around you.

<B>Great read! </b>

I have always been a student of strategy, though never a war monger. Your writings cause a myriad of intellectual topics to come to my thoughts regarding strategy & weaponry. There are so fields & corresponding levels of offense & defense, that I often feel as though that there are an infinite number of battlefields for the present day & future warriors to fight upon! In fact, if I hadn't been such a worthless beer guzzling high school student, in years past, I probably would have devoted myself toward a career in national defense! WATER UNDER THE BRIDGE, many years past now!

<b>anyhow..............................<<<<EMP TECHNOLOGY>>> </b>

Though I do not recall precise dates, ect......EMP (electromagnetic pulse) was generally found to be a resultant after the detonation of a nuclear device (40's). As I understand it, the huge amount of electromagnetic radiation spreading out from a nuclear blast, is likened to a destructive tidal wave, the frequencies are full spectrum for the most part.

It has been the understanding for many years, that the EMP would "burn out" transistors & IC's. In fact, it has been understood that a Nuclear attack would first involve the detonation of several such bombs in the upper atmosphere (I forget which layer (ionosphere???)). The effect of such detonations would presumably be to "burn out" the enemies ability for communication in the military as well as the civilian communications network. If I were going to take a wild guess, I would have to say that our tech boyz in the US have probably got specialized nuclear devices, which specifically target communications in regard to the ability to have a much more devastating effect, by specific design of such possible devices. I say that while assuming that there are possible variations as to the way that the energy of a nuclear device can focused! In other words, when huge amounts of energy are released, there is the possibility to cause the energy to be released in specific wave spectrum rather than in infrared, for instance. HMMMM. ... what I mean is that where a nuclear chain reaction would normally create the large blast & accompanying infrared release (heat), it seems likely that the military has had the "long hairs" working (for many years) to create a nuclear weapon which would release much more of it's energy into the communications band and thus be a weapon that targets an enemies communication networks. Presumably the idea of controlling & focusing energy, thus the way such energy can be released.

In response to Airforce One, I have read and heard over the past years that most US military equipment has some type of EMP Protection. This presumably includes AIRFORCE ONE.

<b>COMPUTER VIRUSES:</b> No Doubt, friend. However I now am moving toward the idea that such attacks would be more from small time Terrorists & Malcontents. Certainly it is possible that "The Chinese," (as an example only) might use such weapons against US, but they would run such an extreme risk if they were to use such a thing as a single weapon, since it unlikely that computer viruses would bring this country down completely, whether the viruses were to be used gradually, or as in all out attack. The risk that the offending country would run by using the technology to destroy the wealth & commerce of another country would be great indeed if they were discovered to be implementing such attacks around the world. The Chinese (as an example only) would be ostracized, criminalized, and black balled utterly by the entire world if they were found to be using such technology against the governments of the Earth.

Hopefully the Chinese Government will eventually come to fully understand that the need for cooperation and peace deserves precedent above the primal and destructive failings, which exists in every race of human being including Asian!

I believe that computer viruses would be used only just before an all out attack upon this country, if at all. The viruses would most likely be targeted at the military's communication network. The communication network of this country is just too large to be devastated or to have a nation wide level of devastation which would allow any attacking country to "walk all over us."

<b>"CUTTING THE HEAD OF THE CHICKEN & LIBYA"</b>

The idea of taking out leadership has been discussed (in various lights) over the past decades. Primarily this pertained to the COLD WAR & the USSR. The reasoning being that in the case of a Nuclear War, it would be unreasonable for the US military to specifically target the USSR leadership in a "First Strike," as the USSR hierarchy would be needed to agree to a Cease Fire. Without the USSR leadership, the diplomats of this country would find themselves dealing with Russian military generals, who probably wouldn't be as interested in making peace as Russian diplomats.

Even if this country (USA) were to have committed a first strike against the Russians, in past cold war years, "cutting the head of the chicken" would have only left a lot of Russian Generals with 'itching" trigger fingers!!!! (The same thing would have (then & now) be true of this country if our leaders were to be prime targets in a First Strike against us).

<i>Libya..........Mommar Khadafi (the Mediterranean fruitcake (fly))</i> ......In this case, as with other thugs & bully dictators across the worldscape, piss on that Nutty Bastard!!! In this case as well as with other infamous personalities....Idiot Amin DADa, Manuel Noriega, Yasir Arafat, Saddam hussein, ........Hillary, Bill Maher (& Big Bill)............ect......anyhow!

The idea of going after the creeps doesn't bother me! Well......maybe a little. It depends on whether the death of say Mommar would make way for someone else that might be more receptive to USA diplomACY!!! You might get someone even worse! This was the situation without our little buddy, Saddam Hussein, during the George SR. Administration. The old Bush administration knew how to jerk on Saddam's chain, thus his death would mean that they would have to "break in" a new tinhorn dictator.

I expect that "Little George" has an invaluable source of friends (including father), to help guide him in decisions regarding asshole dictators across the world today. I say that knowing that George, Jr. becomes emotionally chafed whenever there is a reference to his father. I have seen his obvious responses every time his father has been sharing the limelight with him at public gatherings. Trying to fill the shoes of his father is one thing, but there has been the media comparisons and the ongoing unchallenged, dog-assed lying democrat attacks.

Assassination of other world leaders is not new to this country. In W.W.II, Japanese Admiral Yamamoto (the hawk), was specifically targeted for assassination by the US military under Democrat President Franklin D. Roosevelt. damn!!!! that's right!

To old FDR's credit (or his military General's), the tactic of taking out the "The Hawk" was a logical decision based fact that Yamamoto's death would deprive the Japanese military machine of crucial leadership, thus bringing a quicker end to "THE WAR."

<i><B>ANYHOW///////</b></I>

<i>EMP against the human brain: </i> ?????????...........Hell I have no idea about that one man! I can never seem to get any "real" information regarding the ability of EM to interact (or disrupt) the mammalian (thus human) brain! Since I am an amateur researcher, I do not have a good source of data to refer to beyond the small snips that occasionally come along in the odd science magazine!

This is a subject that I have spent fifteen plus years researching (mammalian brain). What I would have given if I had laboratory data regarding experiments with the mammalian brain, in past years! Most of my more correct theories about the human brain have come from self realizations with virtually no lab equipment!



<b><i>THE REAL THREAT: Bio warfare</b></i>

As I sit here typing away & swilling shots of Russian Vodka, I am reminded every few minutes of my gastric pains of the ulcer that I have shared my life for many years now. There is also the truly incurable "athlete's foot," shingles, arthritis, and a variety of other illnesses, which gather and grow within each human being as the years progress upon him (or her).

As I previously stated, it is the level and thus battlefield that nowadays determines the Top Dog! Bio Warfare is the battlefield today! It may also well be the last battlefield. Allow me to offer my reasoning as to why, as follows:

<i>Rocks, spears, arrows, guns, bombs, ect</i> ..........These are dumb, unmotivated weapons. Even todays crop of computerized smart weapons are lacking. All these primal weapons can be used generally once (computer viruses are a minor exception). In other words, a cruise missile will not procreate offspring that continues the attack after it has expended itself! In a sense, all the weaponry which has been produced by mankind really has been a bunch of limited instruments of destruction that incidentally killed the producers of the opposing weaponry. Though the Nazis (as an example) were our enemies, the real war was between the war machines that were produced by the respective countries. That humans were required to operate the 40's tech war machines is incidental.

When the producers of these war machines were conquered, the war machines could not continue. Bio-war machines do not play this game!

I expect that overconfidence, stupidity, or just plain hate will eventually cause some silly assed group of terrorists or third world dictator to unleash a bio weapon that will not only kill off their enemy, but them as well!

If you think about it, the only defense against such weapons would be for the human race to live on the Earth in much the same way that they would live in outer space. In such a case of warfare, people would be forced to become as alien to the Earth's environmnent as they would be to the vacuum of space. Obviously, there is no way. It is ironic, that we as humans are now on the threshold of immortality, as well the possible conquest of new worlds and yet we are also on the same kind of threshold of absolute destruction.

<b>HISTORICALSSSSSSSSS.......</b>

<i>Prometheus and the power of fire given to mankind.</i>

The destructive fire most likely will come from the Hippocratic desire to heal, as mankind inevitably finds a way to turn even the best intentions into the worst of outcomes. It is this realization of mine that has given me so much sadness and a generally piss-poor attitude as to the future of humanity.

Information and intelligence is always the best defense against hate and destruction. These qualities are rare today among human beings.

<i>The ability to create & destroy has grown faster than the wisdom of those who wield such power.
Perhaps this is the best reason to be religious & thus pray for the survival of the human race, as I do.</i>

First Sexual Transmission of Typhoid Outbreak Documented

By ERIN McCLAM
.c The Associated Press

ATLANTA (April 25) - Health officials say they have documented the nation's first sexually transmitted outbreak of typhoid fever, a rare disease usually spread through tainted food and water.

A Cincinnati man passed typhoid to seven other men in the city who had sex with him last summer, federal researchers said Wednesday. It is treatable with antibiotics, but is occasionally fatal for victims who do not seek treatment.

Typhoid is most often transmitted by swallowing food and water contaminated with human feces, which harbors a type of salmonella that causes the disease. But health officials found that none of the Cincinnati men shared food or drink.

The disease likely circulated by highly risky oral-anal contact among the men, said Megan Reller, an epidemiologist with the U.S. Centers for Disease Control and Prevention.

The CDC labeled typhoid a sexually transmitted disease for the first time at a conference in Atlanta this week, urging infected patients to stop all sexual contact until they are clear of the disease.

Judith Wasserheit, STD prevention chief at the CDC, said the discovery was disturbing but not necessarily surprising.

''We are seeing substantial increases in sexually transmitted diseases among men who have sex with men in multiple locations across this country,'' she said.

Typhoid is marked by high fever, weakness, headache and, in some cases, flat, red spots on the skin.

About 400 cases are reported annually in the United States, four-fifths of them traced to overseas travel. Typhoid is preventable by a vaccine recommended to Americans who visit developing nations.

CDC investigators said the Cincinnati man spread typhoid last summer after catching it during a visit to Puerto Rico in May. It is unclear how he originally contracted the disease, Reller said.

The man then passed the disease to seven male sex partners, she said. An eighth man from Indianapolis caught typhoid after visiting him for the weekend, but said the two did not have sex. How he got typhoid is unclear.

The CDC alerted health departments nationwide of the outbreak in August. The men were uncooperative with health officials, making it impossible to estimate how many other men might have been exposed, Reller said.

''Getting the sexual histories from these patients was very difficult,'' she said. ''What I am sure of is that I do not know the full story of how many contacts the other patients had.''

a great read! That's quite a bit of food for thought. Yes, I agree that biotech is most likely the fear of today and the future. Especially considering the advances in gene splicing. It gives new and gruesome realities to the Andromeda Strain movie.
Given the idea of concentration of blast/radiation in the spectrums you wish to achieve results in leaves a lot of food for thought. This goes in a lot of directions with seemingly endless probable outcomes. Trust that the military has already spent a huge amount of time and money on such.
One of the tasks lent to our Green Berea was the assination mission during Vietnam. It wasn’t always helping the poor farmer and his life/family. It's goals were much the same as the Japanese case you had cited earlier. Only the targets weren't always the high warmonger general. In not all cases were they available for targets on a ready basis.
Computer viruses are only good for a short time. After that signatures are developed to detect and nullify them, bingo, no more threat from that specific one. So as you say it's a use to soften the target prior to really lambasting that goal.
The electrical activity of the brain is not some inside info, but a stretch of the imagination. Though not a long one. As was brought out, you got a weapon; you fine-tune it for the effect you wish to achieve. It actually hit me while I was typing that response.

DAMN WET!!!!!!

You read it before I did a proof read!!!!!!

O'well, that's the general ideas, ect......

<B>OPINIONS VARY... </B>......????????????

HMMMMM??? AH!!!! yes! <I>Patrick Swazy (from the movie: "ROADHOUSE")</i>

You know, after thinking about this, What better way to spread a viral infection then through sexual means? It gets the enemy either way. Either they breed themselves out of existence or abstain from sex and die out. If you were say the Palestines(?), you wouldn’t want an aerobic delivery nor would you want a skin contact method. How devious.

Bravo Everyone! ...This thread Really Rocks!

Anyway, I just want to leave another thought for you kiddies, I am involved in some very heavy research myself, and on numerous ocassions have had my so called high speed internet connections dropping intermitently on a daily basis over the past couple of months.

Several calls, and stacks of invoices latter, Cox Communications is still scartching their heads over this one! (in my last call to them, t hey were lucky enough to detect a "Spike" interferring with my data stream, however they found no direct hardwired devices responsible for the mysterious Spike, and thus will continue looking for answers.)

I have reason to suspect that it is possible that either remote RF, or EMP disruptions (intentional, or not) are responsible for this, and to prove it, I am having some of my research associates fly in, and use their high- tech scanning devices to search & locate the source of these anomolous data stream spikes, responsible for the reported anomolous data stream spikes.

If they are out there, we will find 'EM !

---"12"

Could your spike be something so mundane as a moist underground cable? Or prehaps a loose or dirty connection outside or at the juction box? I wouldn't go so far as to think paranoia first. Ordinary things happen in the world today, just as any other day.

I had one other thought here that I just couldn't leave alone (or maybe well enough alone) in one of the above posts Howard mentioned that

"I do not now see the threat of lesser tech capable nations to "get a leg up", in regards to to EMP TECH."

The problem with this is that the good ol' US of A can't either. So they have shifted a lot of the political focus (read money) away from R&A and into areas of more, shall we say popular problems such as social security. (What a laugh, I see nothing secure about it, other than it's too popular of a program, and vote getter to let die. And yes grandpa does vote) This shift didn't just start last week. Been going on for years. So we haven't really maintained that lead. One of USA's greatest fears should be that some third world yo-yo gets his hands on some of that great tech that Russia has been so freely doling out the dollars for. Our unpatriotic security and research teams who have been so willing to pick up those dollars for just a little file here and there. Allowing that said third world nations might not show their newfound skills right away, it is very possible we could wake up behind the eight ball and standing in Japan's shoes with no defense. Not a comforting thought!

ELF and EMP weapons will unfortunately rear it's ugly head in the quelling of the US populations during times of unrest and discord. US civilians are becoming (if not already) the "new enemy" to the Gov't. This is inherently WRONG but it the natural progression of the beast......

In continuation of this thread, I recommend that you read the following posts; pertaining to your syncronistic perceptions posted accordingly.

I don't believe EMP weapons pose as much of a threat from the 3rd world front or from local government actions. My understanding of the current state of this technology is that the overhead to deplay these weapons makes them unlikely to e used in the near future. The real threat is in the area of RF weapons. These fairly easy to devise and deploy weapons could lay waste to thousands of people in the blink of an eye and leave hardware virtually untouched.

About using Electromagnetic Pulse weapons on develpoped nations. I highly doubt that a third-world country would have the resources to create an EMP bomb. With limited resources, a better fear weapon would be a nuke. Nukes still are the best weapon of Mass Destruction. You get a lot of dead, and get to blow everything up. But back to the subject, an EM bomb or weapon of anysort would be regarded as a weapon of mass destruction along the lines of chem, bio, or nuclear. The reaction of say the U.S. to any country that whacked us with an EMP weapon would be a nuke in return. As i've said before, its Mutually Assured Destruction, (MAD), they hit us, we hit them. The nuclear weapons deturrent would stop this from happening. Don't worry all out TV, microwave, and Internet lovers.

A few years ago, in Soldier of Fortune magazine, there was an article about a military helicopter, that was "shot" down, by possibly, an aimed micro wave type weapon. The helicopter was making a routine flight not far from the Washigton D.C. area. People on the ground described it suddenly coming down very low in altitude, and flying irratically, very slowly. Creditable police and military witnesses on the ground saw some of the crewmen slide open the side door, and standing there looking down and acting in frantic gestures. Suddenly crashing, witnesses on the ground got there immediately, and one was a military officer. He gave a detailed accout in in what he saw, and described the dead crew as being roasted like chickens, even though the aircraft itself was not on fire from the crash, as it was finally flying very low and slowly at the time of going down. No explosions, no aircraft fire or flames. It took sometime for the military themselves to show up at the crash site, but when they did, every body was told to leave, and they took complete and very hard handed control of everything there.The magazine article went on to say that near the area of the crash site, was a defense contractor manufacturing facility, that was working on electro-magnetic pulse type projects. Intense, distance-focused micro wave projection weaponry.The article was much more in depth than I can relate it. The magazine editors would have to be contacted to get a copy of this article. I can't even remember the date that this was published in Soldier of Fortune, but it was indeed published by them. Does any one, besides myself, remember this magazine article?

We have another thread somewhere that has similar discussions. My two cents is that to produce EMP in massive scale will require a nuke. But to produce a focused RF beam can be done from a van. A 5000 Watt RF disturbance will require a simple car battery. Do not try this at home, you will have police at your door step in no time.

But EMP blast is another matter. Anything underground with steel doors will survive the EMP blast. But I am not too sure about an airplane. The primary wave front may get diminshed but subsequent ones will create an induction effect which will knock out all ICs. Just static electricity will knockout your computer memory chips. If a spark jumps at a million volt, goodbye the chip.

The scary thing is about EMP weapons is their simplicity and cheapness of build. A car battery and a microwave oven magnetron are the main parts needed to make a portable EMP beam device.

What presents the most threat are EMP bombs. It is possible to make a compact non-nuke EMP bomb that has a good range of effectiveness.
Stuff a aluminum pipe with explosive. Wind a wire coil around it, which connects to a antenna at one end, and a battery and capacitor at the other.
As the explosive is detonated from one end, and the wave of explosion races along the tube, taking nanoseconds. At the same time electrical pulse is fed through the coil. The shockwave from the explosion crushes the aluminium tube outward against the coil, compressing it and amplifying the pulse, which is then emitted from the antenna before the whole thing is destroyed.
Some bombs like this will crash all un-protected computers within a range of 500 metres (1/3 mile) and permanently destroy most chips within 100 metres! All this from a explosion about that would blow up a car.
The wavelength is such that the radiation will pass through the narrowest of gaps. Any cable to a computer instantly acts like a antenna helping to cook any electronics.
Of course effectiveness depends on the initial input energy into the coil.

Minimal loss of life, but in terms of power its not far from a low-yield nuclear warhead in terms of EMP pulse. But there you have it, a terrorist weapon for $50 - ignoring the cost of the black market explosive.

Scary stuff

In this book, "Quicksilver" terrorists take control of the Pentagon through various means, but their key to taking the Pentagon is to use an EMP bomb made from basicly a coffeemaker shell, a car battery, copper coil, and semtex explosive core. The bomb is launched to maybe a thousand feet in the air, the battery sends a current through the coil which creates a magnetic field. The explosive core detonates moving the magnetic field of 10,000 plus volts through the air, in a crude beam. This knocks out all communications and electronics in the area.

If I were a terrorist and really wanted to wreak havoc, I wouldn't hit the Pentagon, the White House, or anything minor like that with an E-Bomb. If I were a terrorist I'd aim for the New York Stock Exchange at mid-trading time. The bomb would frag all the computers, and crash the stock market. Vola! Instant Second Great Depression for the US and the rest of the first-world.

Pretty nifty, eh?

I doubt a chemical explosion will carry electromagnetic radiation with it. And 5000 watts of power will not induce multimillion volts to fry a circuit at a distance. A mere 10KV will not knock out anything unless physically touched. I think our national grid of electrical power runs at 132KV. Schools with computers are next to those powerlines.

I guess NYSE is attacked everyday by foreign hackers to knock out the system. There are other very simple way to knock out the system like the classic cutting the cable to the building. There are other ways but that requires brain power which they lack (otherwise they would be rich and decadent like us).

Very interesting. However, I do not believe that I will ask how. I might get an answer.

For now I am content that a nuclear blast will supply such and leave it at that. But the prospect that you bring up, that such could be the result, if the terrorists used brain power leaves the door open. Thankfully I live in a small city and as such do not have much to worry about on that scale. (bigger fish to fry elsewhere)
