While times would be difficult, sure, I don't think it would be as easy as you think for some foreign power to just assume control. Look at how the insurgency in Afghanistan turned out, it would be far worse for them here. That isn't even stroking the 2A cock, its just the reality of how armed we are. We may not have ever/will ever turn our guns on our own government, but the tune changes when the only repercussion to armed resistance is literal death or enslavement. The darker races will fall in line a lot easier, but Whites will be a thorn in their side they can't just bomb away - we tried that, and now the Taliban has their country back, all of our shit, and an X account.
