“He has cards to play. “
Like what?
Sure as hall not ground war against Russia, which leaves only missile war, i.e. nuclear.
Idiocy !!
I hate to break it to you, but he has a number of cards he can play. To start with, he has economic cards. He can also increase sales of weaponry to Ukraine and have Europe pay for it, which is exactly what he’s doing.
Sorry for the bad news.
