It sure sounds like Putler is all-in on Ukraine.
As he sees defeat in Ukraine as the end of Russia, so how far is he willing to go? NBC? MAD?
Whatever it is, Russia must lose, as if they win in Ukraine it just makes them want more and escalate until they are stopped, killing millions in the process. More than half a million casualties are already counted for.
The faster russkies are taken care of the less innocent people will suffer.
