Is Putin Losing on the Battlefield?

Putin is more desperate right now than he's ever been. The way this ends is for Ukraine to end it, and the Russians have killed too many Ukrainian civilians. Even the use of tactical nuclear weapons on the battlefield won't change this at all. I would not be the least bit surprised that this is exactly what we have war gamed to prepare ourselves in the event of this sort of scenario. It's never been beyond the realm of possibility that Russia would use a tactical nuclear weapon on European soil.
