> One day people will make this claim about Russia in their current Ukraine war

They might, it would be a sore excuse to nuke Russian territory or bomb Moscow a-la Dresden in 1945. The fact that Americans cannot imagine resolution to war without nuclear violence is exactly how Crimea was annexed and lost. If you ignore proportionality, then your adversary can test your patience and win every time.

This is why asymmetric warfare is so popular in Russia and China, and why it pisses off Americans so consistently. Nuclear weapons give nations a false sense of security, it doesn't protect you against subtle escalation like widespread corporate hacking, political blackmail, proxy conflicts, border harassment or industrial overmatch.
