Unless you’ve been living under a rock since January, you know Russian President Vladimir Putin seems to have gone crazy. He invades Ukraine with about two-thirds of the army he needs to do the job during the mud season. Armored columns pushing toward Kyiv stuck on the roads getting shot to Hell and Gone, Russian mortars and rockets destroying apartment buildings, Russian soldiers defecting and discarded equipment, pulled away by Ukrainian farmers in their John Deeres and used against the invaders. Where does it end?

Not with nukes! At least, probably not. Russia has them. Putin has publicly huffed about their use. Four days after invading Ukraine, Russian nuclear forces were put on alert. Who decides, four days into an invasion with no sign of nuclear threat, to stand up the largest nuclear arsenal in the world? A crazy man?

Maybe.

Let’s look into the nuclear arsenal Putin has decided to put into play.
