We heard this prior to invading Afghanistan to remove the most Islamist and extreme of any arab regime on the planet, the Taliban. Where is the condemnation and arab rage on the streets? Hhhmmm... No self respecting Arab is going to miss the very secular Saddam Hussein or his cronies. Saddam's own people want him gone and they WILL be dancing in the streets just like the happy young girls in Afghanistan who now can attend schools without fear of execution.
This may be true, but I doubt they will embrace a US invading force with open arms either. They have a flaky and fickle history, the Arabs. When the English and Americans landed in North Africa in 1942, and freed it from the French, Arabs cheered the invaders because they thought it was the Nazis. Probably says more about the French than anything else, but it shows how fickle the Arabs can be.
