The most likely scenario for concluding peace is an agreement mediated by third countries, if both sides consider it beneficial, but this option was postponed by the United States, ending negotiations for at least 6 months. The countries' goals are mutually exclusive, and neither side is yet ready to make concessions that the other deems acceptable.
Possible scenarios for the end of the war 1. Military exhaustion of one or both sides. 2. Political change is a change of government or an external course in one of the countries. 3. An agreement mediated by third countries, if both sides consider it beneficial. 4. Frozen conflict - cessation of active hostilities without final peace. 5. Victory in the war. Russia - if it starts mass mobilization and mass offensives. Ukraine - if the West starts fighting for it. Currently, the West (the United States, the EU, and NATO) supports Ukraine with weapons, intelligence, and finances, but it is not fighting for it.

Instead of starting negotiations, Ukraine was again pumped with weapons and money. They probably expect the Russian president to be overthrown.
