Check out Tommy Franks autobiography. Rumsfeld didn't write the war plan. Franks and his staff did. Rumsfeld (and Bush) agreed to it. The same thing appears to be happening now with the occupation/transition.
Rumsfeld is claiming he is not dictating tactics (unlike, say, McNamara). I believe him.
He is also saying he is leaving the decision as to what the troop level should be up -- which appears to be the big part of the controversy -- up to the generals in Iraq. Again, I believe him.
Good, well written book.
Last question from Bush to Franks, "Do you have everything you need?"
His story is quite fascinating. He was hired out of retirement in the summer of 2002 to serve as "Saddam Hussein" in a massive "war exercise" that was set up to simulate a major U.S. military operation in the Middle East.
The original scenario began with Van Riper thwarting the main U.S. invasion and sinking a U.S. aircraft carrier in the Persian Gulf, and ended with the U.S. military forces getting mired in a long, drawn-out guerrilla war in the region. The Pentagon leadership that was overseeing the exercise went back and "fixed" things so that it would end up with a swift U.S. victory and minimal casualties.
Van Riper resigned in disgust when he realized that the Pentagon wasn't trying to conduct an accurate assessment of the situation in the Gulf region -- they were looking for a pre-determined outcome.
