I think the west needs to avoid being over-zealous in this fight, and let's face it we are heavily involved. This war seems to be quite personal for Putin, and if he is pushed back too hard, he may act irrationally, or be ousted, and then who knows what chaos may ensue. Europe should accept that cheap Russian gas is history. And so, a long drawn-out stalemate in Ukraine is maybe the best course, for everyone except R…
The issue with waiting out Putin is that it assumes any successor would be more likely to go for a peaceful/negotiated solution. I think this is shortsighted as the most credible opposition figures take a far more hawkish stance, which would increases the odds of an all-out escalation.
Far better to keep things on a slow boil, so when things eventually shift internally in Russia, there is at least some stability externally. And when they do shift, it may be in the other direction, with the hawks washed away by popular dissent, or just fatigue for the war.
