That is not a new charge:
(CNN) — The Bush administration began planning to use U.S. troops to invade Iraq within days after the former Texas governor entered the White House three years ago, former Treasury Secretary Paul O’Neill told CBS News’ 60 Minutes.
He had to finish Daddy’s war.
That's my recollection, also. I know I was puzzled that W seemed hellbent on invading Iraq, even before 9/11. All too often in government and many other areas I'm afraid those in authority often decide what they want to do, then give orders that their underlings provide the rationale for doing it.
