Nobody knows what Putton is going to do. The sanctions are the right thing to do, a it could take months or years. If he topples the current government in ukraine and replaces it with his lackeys, that's going to be harder to get ukraine back its sovereign status among nations. Whether it could escolate to arm conflict, or whether he would between the west and russian forces,. much less escolate to a nuclear exchange. Just from i know, i think he wants to cobble together the old us. S r and stop there. And nada will, course, not let him go any further than that.
