Some are. Most aren't. In Iraq for example, if the terrorists enjoyed majority support of the population, we'd have to be extremely ruthless to suppress it. As it is, we get a handful of daily attacks, some successful-most not, and we are routing the sucmbags with the assistance of the Iraq soldiers and just as importantly, the citizens are ratting them out.
In Turkey, despite having an Islamist party in power, you and I could safely walk the streets of that country and thousands of americans live there.
In America, despite the definite existence of sleeper cells, the vast majority of muslims are here peacefully, and have every intention of remaining so. the celebrations by the local Iraqi populations in the Seattle are when Saddam was captured was fantastic.
The Kurds, also muslims, love the USA.
the Iranian people, by and large, are the most pro-american muslims in the ME and will celebrate wildly when the stinking mullahs are hung from lamp posts.
