They take territory and replace local governments just by threatening to call you racist. And you think people are gonna band together in militias or whatever and face off against literal combatants with firearms. They're not gonna do a fucking thing. Anyone who'd actually fight would go join our military, everyone else would sit under occupation and wait to be liberated.

Doesn't matter though cause that other guy was right, there wouldn't be an "invasion" like this, countries become communist from the inside.
