I think the probability of an all-out nuclear exchange is still quite reduced, but if the capability gap between Russia and the US extends considerably, this probability will increase from the current infinitesimal level to a non-negligible one. Other events that were once considered unthinkable (DJT, Brexit) have come to pass, so never say never. With that said, how can we get to such an extreme event as a nuclear exchange? I think that whenever there is a military crisis in the world (Iran threatening to resume uranium enrichment ?) the POTUS asks his advisors for options. The spectrum of options ranges from PR spin machine, to diplomatic pressure, to military operations. All options will have listed their pros and cons, their best, base and worst outcomes. They will be judged in isolation and weighed against each other. After this careful comparative cost-benefit analysis, the POTUS makes the decision. Now all things being equal, if the military gap between the US and the opponent is larger, the armed response options will comparatively have a better cost-benefit ratio. The more impenetrable the ABM defense becomes, the more the military option will look like the better deal. Now the vicious cycle is that, as the military option is chosen more often (how long did it take DJT to send an aircraft carrier towards Iran?), the more tensions will appear, and the more crisis situations will emerge. Some of them will be de-escalated, but some will escalate to various levels. Sometimes cool heads will prevail, but sometimes the grown-ups will have left the room already. One day Russia might do something that would trigger Nato's article 5 [1], and the US will have to respond. You could say that we've been in many situations like that in the 60's, 70's and 80's, but the military gap between the US and the Soviet Union was never close to what it's now, and what will become in the coming decades. Ok, ok, but nuclear, you say? Well, the US has dropped about 100 bombs in Nevada, just 60 miles from Las Vegas, and it was no big deal. A few (hundred) small-ish nukes going boom in the middle of Siberia will result in some condemnations from some pacifist organizations, but as long as there is some reasonable casus belli and minimal civilian collateral damage, people will move on quite soon.
