Yeah, it's absolutely the fault of America, Israel, and the West that a terrorist manual written in the 7th Century commands its adherents to do things like this which they, in fact, do.
Then the liberals will trot out their cliched retort about bigotry and violence from Christians and Jews. Well sure, Christians and Jews have committed acts of violence before. The key distinction that the Left deliberately ignores is that when Christians and Jews do such things, they are going against the professed beliefs of their faiths. When Muslims do it, they're doing exactly what their faith has commanded. That collection of 7th Century asswipe that they call a holy book reads like a script from a Conan the Barbarian film.
