I'd much rather have the US heavily-handededly knock down the Russian economy than the alternative of involving itself militarily.
People might say: look how West is behaving, when America invaded other countries or when NATO bombed Yugoslavia no one sanctioned them, but they are doing it to us, they hate us

Nobody has done anything after the fake bombings before the Cechnya intervention in 1999, which at least is in their own territory. But then again silence in 2008 after the Georgia invasion, and again in Crimea in 2014. They are using their nuclear arsenal as a free pass to invade everyone and break every treaty.
I think it just became unsustainable at this point. And honestly this is the best we can do to help without making things worse.
