Wired's Danger Room has an article (U.S. Military Taught Officers: Use ‘Hiroshima’ Tactics for ‘Total War’ on Islam) about a course that was given at the Joint Forces Staff College on Islam.
The course puts a lot of stress on texts in the Quran about spreading the Islam over the whole world and killing infidels and it recommends harsh measures to counter that.
Sorry to see such ignorance. The bible has radical passages too if you know where to find them. "Force them to enter" was once a favorite excuse to put people under pressure to convert to Christianity. Just as with Islam what counts in the end is what people do with it. And there are many peacefull Muslims too.
