Very profound but unlikely to move the needle in the immediate term. Such an acerbic (yet very honest) outreach is unlikely to get Putin to move while hoping his ballistic missiles are ready to change the tide by 2027.
Ukrainian President Zelenskyy sent an open letter to Putin. It includes some hard facts unpleasant for the Russian dictator. However, he also proposes a direct meeting for ending this war, on neutral soil, e.g. Switzerland, Tรผrkiye or an Arab country.
Ukraine is having the strategic initiative. Putin is getting humiliated again and again. The war has reached Moscow and Saint Petersburg. Putin is under pressure, and even some Russian allies must feel it by now that Russia cannot win.
If Putin refuses then it would give Ukraine even more political backing. If Putin gives in, then during a phase of weakness. A clever gambit by President Zelenskyy.
