Hard disagree. Guerilla resistance has proven itself surprisingly effective against modern militaries. Multiply that by a military which would be going to war against its own citizens and you have a very uncertain situation.
Yes, if the military was targeting you individually you'd almost certainly be fucked. But a guerilla resistance spread out over a continent would be very difficult to eradicate. Just look at Afghanistan.
I think there are enough stories of armed religious groups raided by three letter agencies to prove otherwise.
