what saddam did is strongly dissaproved by all muslims, but all this happened along time ago, so why did US act now? not getting enough oil or riches perhaps?
Better late than never I think. And now was a good time, because Iraq army had become so weak.
Yes, sure they need the oil. But they will pay money for it. Wars cost a lot of money so I don't think they would've attacked Saddam it if there were no expected financial gains for them.
