The Russian Federation did leave Ukraine be. It was only after Western meddling, a coup, a civil war, not implementing agreements, toying with NATO membership, and resuming a civilian shelling campaign that the RF invaded.

The imperial core Western powers poked and prodded and used Ukraine as a pawn until the RF hit its limit.

Given that you likely live in one of the countries doing the relentless escalation, why not work against them doing so?
