Putin is just the village idiot.
Most likely scenario is that he will launch a small tactical nuke in Ukraine just to ramp things up and make everything scary.
But NATO will turn Moscow into Hiroshima so Vlad won't get to use his hypersonic. Hope that does not mess up his Victory Day parade.
Yeh, never underestimate the genius of Putin.
Classic case of underestimating an opponent. Good luck!
