It will take - and I fully expect it to happen within the next two to three years - detonation of a nuclear weapon on US soil to get the sheeple's attention.
I highly doubt it. The muslims are content with guerrila warfare. If they detonated a nuclear device in the U.S., they would be signing their death warrant. Nobody even remotely associated with islam would escape, and our government would be powerless to stop the ensuing battle.
