I’m simple on that notion: Russia is our adversary.
They have assassinated people in the EU and UK. Sabotaged our pipelines. Paid anti EU politicians. Threatened EU powers. Shot down civilian flights. Made plans to invade the Baltics.
They are an adversary. We have weapons and an army. We should neutralize that adversary.
Russia has currently lost momentum in Ukraine. So they are seeking a temporary peace, to rebuild. Logic dictates that we start behaving as their adversary. To not give them any benefit, and build on that momentum to keep them diminished.
