Yes, I am serious. What exactly do you think anyone is going to do about it? There isn't an international court with any power to do anything. There is a cold-blooded murder in charge in Saudi Arabia, and there is ample proof he ordered the assassination of a reporter, but nobody does anything about him.
I've described exactly what will happen, and when he does remove his forces from Ukraine, the west and NATO will celebrate their resolve and quietly lift the sanctions, which are the only real punishment he's dealing with. He will get away with it and emerge stronger on the other side.
