Now is not the time to end the war. Here is the main reason

Neither Ukraine nor Russia is in a stalemate. Both sides continue to recruit people, both sides have resources and funds, and both sides are conducting active offensive operations (Russia on the battlefield, pushing with more numerous infantry, Ukraine — on a strategic level, striking critical targets deep within Russia).

An agreement or treaty is a fixation of what is actually on the ground, not the other way around. Behind the politically correct and veiled phrase "stabilization of the front is needed," it is implied not that the front is currently moving (strategically, 10-20 km forward or backward — this has no significance), but that there is no stalemate situation. Simply, no one at the high diplomatic level says this out loud.

It is obvious that the economic and material situation in Russia is worsening and should eventually have an impact. In this regard, Ukraine is not in a dead-end situation, which is why it does not agree to a deal under any conditions. It literally dictates the terms: okay, freezing, but we exchange here; freezing here, but no recognition; continuing the course towards the West; continuing the army and militarization, etc.
