I already wrote in this topic that the US and NATO will respond to a nuclear tactical attack, and their position is quite clear - the response would be exclusively with conventional weapons against all Russian targets in Ukraine - but given that Russia has annexed parts of occupied Ukraine, that would mean that NATO attacks Russian territory, which means that Russia has the right to retaliate with strategic nuclear weapons, which means that all large cities in the northern hemisphere would become targets.

The simulation was not done a few years ago, and that Plan A would actually be the end of the world as we know it today. The fate of the world, as I have already written, is in the hands of a man who is completely obsessed with his idea of a great Russia at any cost, and on the other hand, a senile old man who can no longer appear in public without causing some new ridiculous situation.
