Putin doesn’t have the time. Too many weapons are pouring in and the Russians aren’t all they (or we) thought they were.
The Russian troops don’t seem to be up for this. Russians getting killed to invade and fight against Russians? Why? Neo-nazis? Where?
So long as the Russians can push buttons from a distance they are OK with the plan but facing off eye to eye with people who look and talk just like themselves who are defending their homeland just as the Russians would defend Mother Russia? Not so much.
I hope I am right.
