you asked for one excuse as to why we should not go in. well i never thought my feelings would be summed up so perfectly by president bush but here is your reason

...to go along with the speech just given:
"We should not march into Baghdad. To occupy Iraq would instantly shatter our coalition, turning the whole Arab world against us, and make a broken tyrant into a latter-day Arab hero . . . assigning young soldiers to a fruitless hunt for a securely entrenched dictator and condemning them to fight in what would be an unwinnable urban guerrilla war. It could only plunge that part of the world into even greater instability."

--from "A World Transformed," a 1998 book
by the first President Bush.

now where are all the iraqi's that will great the soldiers with flowers? this was a giant mistake and will cost many more american lives than the soldiers you see on tv..

ps add bill gates to your list... he dropped out of college as well.
