The dems would simply pull out and watch the middle east change to one huge IRAN.
Bush failed to comprehend that both the Iranians and the Shia majority are one and the same. The current Iraqi PM is a Shia who attempted to kill Saddam in 1980 and subsequently fled Iraq to save his hide. We (US) put this dope in power and now I believe we regret it, because he will side with Iran.
Saddam was able to keep a tight lid on sect. fighting by ruling with an iron fist. Bush opened a can of worms and has no way to curtail the onslaught of fighting. (Colin Powell clearly understood this fact, but was ignored by Bush and Cheney.
Remember, prior to invading Iraq, Bush had no idea about the difference between a Sunni and a Shia. He thought they we're all "just Muslims".
As C. Powell told Bush........"you break it, you own it."
