What happens if we flip it around, do you think that countries in the Middle East feel there is a real threat from American Imperialism?
They do, which lead to the attacks, which leads to Americans feeling threatened, which leads to bombing and overthrowing government, which leads to the Middle East feeling much more threatened by American imperialism, which leads to more attacks and so on...
There may be a threat from radical Islam, but it does go the other way too, whether either or both threats are real or perceived has a lot to do with what side of the line you are standing on.
But in my view, I don't want there way of life imposed on me by force. They probably don't want mine imposed on them by force either. But now we have to sides using force to try and prevent the other side from imposing its way of life by force. I can't see how anyone is going to "win"
And as far as radical Islam goes, I think the more threatened Islam becomes, the more people will turn to the more radical views of it. The same thing seems to be happening in the States with Christianity, certain branches science and atheism finding a voice seems to have brought out more fundamentalist views, with things like "Creationist museums" sprouting up.
The US where the good guys as long as they where chasing down Bin Laden and terrorist groups. Once it became about Oil and Islam the worlds opinion changed. The more it becomes about Islam, the more Muslims are going to feel threatened and tempted to join that cause to protect there beliefs, as I imagine Christians would if it was Christianity that was in that situation.
