Agree.

> Europeans could do it themselves - they have ~~ 20x the economy of Russia

Europe isn’t politically capable of decisive action. By design. Some European countries could, but I’m not seeing a proximate future where Europe is-and is treated as—a great power.

> escalatory risk could be further decreased by offering Russia a permanent security treaty based on the old borders, with disarmament on both sides

What do you mean by disarmament? Ukraine and Russia will obviously maintain arms after any peace. They just won’t be blowing each other up.
