Sure you can. A few nuclear airbursts to knock out communications and electronics and Americans would be lost like lost sheep.
And since the morons in DC have reduced our military to a handful of over-sized bases, take those out, and then take over a few key cities, and then the democrat half of the nation will bow down and take it up the arse, the gun free, tranny f@ggot bitches
At this point finishing off our military would probably be bad for them.
That would release the civil population and we outnumber all of the world's armies combined.
