Now that it's the West, media just glances over the fact

Which media are you consuming? Talkshows discuss that for hours and News shows always mentioned the problem of cluster ammo.

the fact that these munitions cause so much civilian death

No civilians will get killed by this munition from the US. Ukrainians use them on invading soldiers on evacuated land.

Russia used cluster ammo first and uses it for offense. Ukraine is using it for defense.

That's the whole issue: Ukraine changed A LOT in the last 30 years and wants to belong to the west. And the west thinks so aswell. But Russia can't accept it and has to learn once and for all, that bullying a satellite country doesn't bind it to russia (Watch Belarus, it'll be next). Also Russia thinks it can just force Ukraine to like russia and associate with it. Europe can't tolerate this and will go to full lengths to teach Russia.

Now you are promoting to forsake a weaker victim for the sake of peace (your peace, not peace for Ukraine). You're completely ignoring what russia does to civilians on conquered land. History (Germany, Afghanistan, Syria, Mali) should make it clear that the killing won't end when Ukraine fails to push Russia back.

Quite the opposite. Bucha shows, it will just start the slaughterfest.
