I just hope Ukraine knows what it is doing, as it’s calling the bluff of a nuclear power. I don’t think Russia will nuke with anything big, but they might give the go ahead for small scale tactical nukes. Then again, Russia was already training for their use, so nothing lost and this means that if they use them, they might have to use it within their own territory and assume those repercussions. Best case, corruption has already disarmed any possibility of using them.
