People still are not listening. George W Bush and his cabal of neocons certainly did not listen. He came into office with the idea of invading Iraq and is actually quoted in saying so, that is what he did. He ignored anybody and everybody who told him differently and proceeded to march the USA into the tar pit we had managed to avoid. Right wing nutjobs are now trying to say it was the democrats that did that. Utter BS They either can't or won't deal with the truth. Trying to pin Iraq on democrats is mere election minded claptrap.
Fear was ginned up by the neocons to cause people to accept possibly the worst decision by an American president in my lifetime.
Here is where Brent Scowcroft (one of many) warned Bush publically and emphatically about invading Iraq:

Somebody earlier said something about Presidents that think they know more than their generals, well Bush is the posterboy for that remark.
