I don't really buy nuclear talk. He wants to talk a big game but he's defined a clear redline and NATO is respecting it. A nuclear strike on Kyiv would've worked back at the start of the war when they were still scary, to force fast capitulation, I don't know if it'd have that effect now.
Though at the same time probably worth considering that Putin doesn't seem to be operating on cost-benefit analysis. I'm a fan of taking people at their word and Putin's made it clear his problem is with the existence of Ukrainian nationality as a concept. That's emotional/deontological thinking, not instrumental, and that changes things a bit. That kind of thinking got us 20 years of misery in Afghanistan.
That's also why I don't buy this thing I keep seeing from Chomsky and friends, the "US is using Ukrainians as cannon fodder" thing. What's the alternative? Cause it's not giving up, we all saw the plan for an occupied Ukraine and it's tantamount to genocide. The systematic eradication of "Ukraine" as anything more than a section of western Russia. Irrespective of America's involvement (Of course America's primarily happy to see Russia bleed over this, and yes that's not a good motivation) I don't see an alternative, you can't bow to a program like Russia's, it's a non-starter. But that's Chomsky, he's got some really good ideas and thoughts on things but he's always had a giant blind spot for non-western imperialism. And other similarly dumb people.
The snake island stuff has been interesting, the Spetsnaz chopper that got blowed up, the way the troops were all fanned out and prone around it makes me think snake island is a complete shitshow right now. Along with Ukrainian jets flying right the hell over it on bombing runs and the big Z somebody's painted on the island, it looks like they're completely out of contact with the mainland and nobody has any idea what's going on. Maybe they'll get their own go fuck yourself warship moment soon.
