I hate how “anti-war” has been hijacked by these people to mean, let imperialist countries invade whoever they want with no consequences. (in the case of tankies, any imperialist country that isn’t in NATO).
Just to offer you a perspective on what other people think, not that you asked for it but idk, don't read if you're not interested :) I'll be brief.
America not having their back might bring about a truce treaty, which would stop the war, the bombs, the people getting killed. I think across the political spectrum from "tankies" to Trump supporters and everything in between, lots of people are hoping for a fast peaceful outcome.
