> Russia isn’t going to go nuclear unless Ukrainian forces start heading towards Moscow. They would sure like you to think that they would, though.
No, Russia isn't going nuclear unless Ukraine will move into Russian territory. While Putin annexed parts of Ukraine to be able to use draft soldiers there, it still part of Russian territory in his mind and minds of many Russians (starting with generals and oligarchs ending with ordinary citizens). So use of tactical nuclear weapons can't be ruled out.
