Fifteen thousand armed jihadists kept the entire U.S. military tied up in Iraq for ten years, and you think they can just kill off 8 to 10 million armed Americans who would fight back?
For crying out loud, think it through.
Did you read the Gulag Archipelago? For crying out loud I thought not. The key is "fight back." How many of us followed Timothy McVeigh's example? Why that would be ZERO. Because we aren't "fighting back."
Look at Boston and the Gestapo tactics used by the JBTs looking (unsuccessfully) for the bomber. Did you hear any outcries? No of course not. We're all waiting for the sudden event that will trigger some sort of response. Well it's the slow boiling of the frog. By the time the frog realizes he's screwed it's too late. You try "thinking it through."
