There’s nothing to negotiate here. Russia wants to conquer Ukraine and they’re indicating their next move is on Moldova. They’ve also issued what amounts to an ultimatum to NATO to withdraw from all of the former Soviet slave states and that’s a non-starter as well.
The correct answer to Russian threats is to meet them with force and resolve. Just like we did when those pricks used to be honest about being an Evil Empire.
No, we never met them head on within a single country. We drew a line and dared them to cross, which they didn’t. We’re closer to war with Russia now than we ever were during the cold war. If Ukraine is worth a nuclear war which could kill everyone in the U.S. and half the world, it must be pretty vital to our existence.
