Actually, the biggest tool in the box preventing conflict between nuc powers was diplomacy.
A tool we the West but essentially the people running the Biden show….no longer choose to employ.
Russia has now developed 50-100 MT nucs to try to keep diplomacy going among rational leaders, or for when they finally decide our leaders are no longer agreement-capable and are determined to destroy them
No it isn’t, the real chance that they couldn’t beat us to take Western Europe is what kept them from trying.
It was military might and a tough Presidential stance that made Russia let that window pass.
By the way, President Trump set us on a nuclear buildup against the Russian threat that we are still on.
