Ceding land to a foreign aggressor is not a viable off-ramp. Get real.
This is nationalist rhetoric. Claiming to be a socialist and yet obsessing over the borders of one bourgeois state over another bourgeois state is one of the reasons you are being called a liberal here. You are a nationalist cheerleading for one group of billionaires to rule over the people instead of another group of billionaires, all while hundreds of thousands of people get killed in the name of that. Meanwhile socialists are out here saying we don't want people dying and do not give a fuck what borders exist as long as people aren't dying, the best solution is the quickest and fastest way to minimise death.
You are defending the state, not people's lives. You are sacrificing people for states and borders. You are a bourgeois nationalist, and you would have advocated for the same thing in every past conflict. You're not even a social chauvinist and they were shitbags, you're just straight up nationalist.
