Think about this.....
One of two things will happen eventually. Putin will either win or not.
What is worrying is what he will do on the way to either outcome.
The Ukes' won't give up and won't care if he says part of the country is now Russian. They will fight to reclaim it.
Putin will then claim attack against Russia and use Nukes ....
The only way out of this without it going nuclear is Ukraine surrendering, which plainly isn't going to happen.
So.. Buckle up.
