Because it doesn't make good press for the Exxon BP Halliburton Mc Donell Douglass WAR.

In the meantime, I'll rasie a pipe to our surgeons. They do what they have to. A finger here, a leg there, a chunk of someone's brain on the side ....

I keep waiting for the announcement of a new TV series: M*A*S*H: Iraq, to be followed shortly thereafter by a gruesome trend in reality television the only saving grace of which is that if doctors in wartime act like cops on "COPS", their patients will die in droves, so they can't really put up the same kind of BS.

But how about the MASH: Iraq episode where Homeland Security issues an arrest warrant for Radar O'Reilley for shipping strange mechanical items into the country? (Radar tried to steal a whole jeep, one part at a time, mailing the pieces home to Iowa; I think he got away with it, too.) Or come bust the Swamp because agents suspect the still is really a bioweapons plant? Or when Hawkeye is arrested and sent to Guantanamo as an enemy sympathizer ....

Oh, yeah. These are all volunteers. That's right.

There goes that idea.

Because there’s no enough security to escort him during the visit!
