It's such a mess.
Who knows what's going on in the background, but from my perspective, none of the western leaders seem to be giving any thought to what is Putin's exit option, other than "Win the war at all costs and be seen (domestically) as a great liberator and nationalist hero" or "Go home with your tail between your legs, face domestic upheaval, revolt and your probably overthrow and likely death". And yet somehow we seem to think he will just decide to choose the latter??? Mind boggling stupidity on our part.
Unless we (the west and Ukraine) change course, then I think the fall of Ukraine to the Russians is absolutely inevitable (barring some shock assassination of Putin in the next week or so, which we must assume is a long shot (no pun intended)).
