It's the first time it's come hand-in-hand (same day, even) with the announcement that they'll shortly be considering 4 oblasts of Ukraine to be "Russian territory", thus creating the circumstances he laid out under which Russia could use them.
And its the first time (IIRC) its come directly from the President since the Kharkiv/Kherson counteroffensive.
Fair enough. Otoh, after you threaten to launch nukes x number of times and then make no indication you're planning to do so(fueling missiles, sortieing the fleet, etc?), Eventually it feels like "put up or shut up, Vlad".
Honestly I have to wonder how much of the Russian missile forces are capable of hitting thier targets and I suspect Putin has wondered as well. Because Russia is not impressing with their ability to maintain or supply thier forces.
Don't get me wrong. It would be catastrophic if Russia launched a first strike no matter how many nukes go off. I just suspect the number of nukes capable of reaching their targets ATM is probably a bit lower then the official numbers.
Russia can make life miserable for a lot of people in the event of a nuclear strike. Russia will be wiped off the fucking map if they do. don't want to test this. I hope the Russian brass or even Putin don't want to either.
This isn't 1945 anymore. You can't drop two nukes with the implication you have a hundred more ready to go(but you actually don't) and get away with that. NATO will freak the hell out and go to high alert the moment that happens and Putin can't "sorry, is joke" out of that. He'd be a fucking idiot to go nuclear on any thing less then full war footing/full "no shit" mobilization because every Russian military unit suspected to be nuclear armed will go to the top of the "Kill this first" list. We're very likely at Article 5 territory there.
On a related note, I suspect the Pentagon doesn't see Putin threatening to nuke shit as credible because of what we're not seeing. That being:
-We're not seeing Naval vessels and fleets putting to sea suddenly and ahead of schedule AKA with with some massive urgency.
-We're not seeing NATO bombers being prepped for immediate takeoff and or spending a lot of time in the air just outside of Russian Airspace. Particularly the Heavy ones Like B-2 and B-52s that are capable of carrying nuclear payloads.
-We're not seeing reservists called up suddenly.
-We're not seeing the DEFCON getting steadily/sudenly lowered down to 3...2....1(Game over).
These are all things we'd be doing if we seriously expected Putin to drop a nuke in the near future, both as a "Don't even try it, fucker" warning and a hammer ready to drop if he did because if Russia uses one, we're going to assume they're going to use more and that would very, very likely be the line in the sand for NATO intervention.
Now, if we start seeing the above, get worried because shit is going down at that point.
