But neither Jon Banks nor Richard Smith have answered my previous question. If we reduce our support for Ukraine, the Russians will conclude that it is the threat of Nuclear War that caused us to back off. So, when is the best time to stand up to the Russians? Now? If Russian later assaults Ukraine by land again in ten years? Or with Nuclear Weapons in one year? Or attacks the Baltic States, or Finland, or Poland, or Germany? Or is it best not to stand up to them at all and allow Russia to overrun all of Central Europe right up to the French border? What is our best option and why?
Given that Russia can't even conquer all of eastern Ukraine after 10 months of war against a smaller and poorer country (albeit a country with intelligence and military aid from NATO countries), why do you think it's realistic that Putin would try to invade a NATO country next?
This war has exposed Russia's weaknesses in terms of waging a conventional war. They're in no position to expand their war beyond Ukraine. Unfortunately for Ukraine, they're not a NATO member state so they're on their own. And I doubt that they can win the war. The best case for Ukraine in terms of what is realistically possible is for them to fight Russia to a stalemate.
So to answer your question, no, I don't think there's a realistic threat of Putin attacking a NATO country any time soon. I don't think we need to "stand up" to Russia. They're not attacking the US or our national interests.
This war is a regional war being fought over regional issues. It's not America's fight. Regardless of the outcome of the war, there's very little at stake for us. I also don't believe Russia intends to nuke Ukraine. They are doing more than enough damage to Ukraine with conventional weapons.
Russia is not the Soviet Union. Russia today is a corrupt and declining country. It doesn't do the US any good to exaggerate or overestimate the threat to us posed by Russia.
While I don't agree with the policy of confronting China militarily, they are far more formidable as a rival to the US than Russia is...
