I think you're partly right. Because they're relatively wussies yet want to remain elitists in the larger, pan-world aristocracy, they've given our tax dollars to most every federal agency to militarize (think of "Africanized bees") with plenty of ammo, so, it may be that they'd try to flood us with blue helmets from the UN. That would be bad and hopefully short-lived. But, nukes could be used to make an example of some of us and millions could die if the Left gets Russia, Iran and the Chinese to help subdue "revolting masses of Conservatives," all as cover for their vision of an all-encompassing, one-government world.
Obama is setting things up for the AC.
