The heart of the beast is Saudi Arabia, not Iraq. Without Saudi Arabia's financing and blessing, there would be no Wahabbi movement, without the Wahabbis there would be no radical jihadis.
Saudis don't have transferrable weapons or an army.
If we had gone after SA do you think Hussein would have stood by? Or Iran? If we had gone after SA it would have lit a huge fire in all the islamic nations. If we had occupied Mecca what would have happened?
Agreed on the Wahabbiness of SA but we need the oil.
I think we should have launched a Manhattan style program to get us oil independent so we could tell them either give up the radical islam or the west buys no more oil. Then they would have no money to spread their hatred.
