If NATO attempted to enforce a no-fly zone over Ukraine, that would probably be the ideal provocation to get Putin to use his nukes. He already strongly hinted this a few days ago.
Nonsense.
NATO has more effective and better guided nukes than Russia. Any attempt by Putin to escalate the conflict to nuclear status would lead to instant retaliation and annihilation of his regime. Putin knows this full well, and will NEVER go there. He will saber rattle to deter future containment efforts, but that's as far as that will go.
If there is one thing in this world you can rely on, it is
dictators obsession with self-preservation. Self-preservation even trumps their self-importance and ego-massaging. Even Saddam, no matter how belligerent and psychotic he was, didn't want to die. Saddam hid in all sorts of sh!t holes for ~9 months after he lost his country until we found him.
Putin would never do ANYTHING to endanger his ability to stay in power.
He may have a skewed sense of reality as to what he needs to do to earn a place in history, but he is not suicidal in any way. Thus, he would NEVER use nukes. He WILL threaten to do so and sabre rattle till cows come home, but will never touch them, since he knows that will be the end of him.
I know it's a total pipe dream, but wouldn't it be nice if the world would rise as one, and demand the removal of all nuclear weapons. I know, I know, Pandora's box only opens, never closes. But if Putin didn't have 6000 plus nukes he never would have done this.
In the history of the world, no technological advancement has ever been "forgotten". Once a discovery is made, it has been fully explored for its maximum productive as well as destructive potential.
w.r.t Putin's motivation, I am pretty sure he would have done this anyway, with or w/o any particular types of weapons in his arsenal. His Soviet predecessors moved in on Eastern/Central Europe without nukes (developed later), because they had the desire to expand their "sphere of influence" by military means. Putin is a Stalin/Hitler wanna-be (same totalitarian sh*t, different flavor), and he is following in the footsteps of his idols.
In a perverted way, his actions are perfectly logical. US did little to nothing in response to Russia's previous invasions: Moldova (1992, 2002), Georgia (2008), Syria (2015), Kazakhstan (2022), and Ukraine (2014, 2022).
If we did nothing to stop Russia earlier, in Putin's head, the US and the World are way over-reacting now!
How far is US willing to go to stop Putin now (as opposed sanctions that will take 2-10 years to work)?
I'm not sure, but the State of the Union address later today might provide some clues.
