It is a good idea to not damn the facts but it is pure prejudice speculation that Cheney and Bush wanted war with Iraq. Hussein and Al Quaida hated each other, no doubt about it. But they both hated the USA more and both called for the destruction of the USA. Iraq would be a great enemy of the USA if we had not taken them down. That is a reason we should not allow Al Quaida to take over Iraq with an oppositional attitude to the USA.
Obama will be forced to eventually take the middle of the road approach like Bush did if he is going to protect us from a world wide attack on our global interest, don't you think?
