BULLSHIT! YOU KNOW NOTHING ABOUT STAR WARS! YOU DON'T KNOW ABOUT THE SUN CRUSHER, GALAXY GUN, OR WORLD DEVASTATORS NOW DO YOU? Let me quote Base Delta Zero:
It denoted the most severe of several levels of destruction that could be directed against a center of resistance, and involved laying waste to an entire planet by orbital bombardment, reducing the upper crust of a planet to molten slag or in extreme cases going so far as to atomize the planet's top-soil.
A Base Delta Zero fleet bombardment was regarded as one of the most devastating operations that the Imperial military was capable of, and unlike other Imperial military codes, the designation was not subject to change, so that there was never any confusion when it was issued. Due to its effects, BDZs were considered a last resort.
And the Death Star having a bigger hole in RotJ? Are you smoking crack or something it was UNDER CONSTRUCTION and that hole would have been closed.
Turbolasers are lasers? YOU ARE ON CRACK. It is stated turbolasers are a fucking name damn it. They fucking shoot plasma! Besides your pathetic shitty ships do 100 gigawatts and ISD's do 1.2 teratons per turbolaser. Hey retard, did you ever hear of the word google? An ISD can destroy a planet in less than ten minutes. The DS would destroy your pathetic Federation.
