Yep. Anything short of Russia’s total retreat is unacceptable, and ideally they’ll be forced to pay reparations as well.
Something often forgotten by the “stop the war now” crowd is that the war could be over tomorrow if Russia withdrew. This war only exists because Russia invaded another country to stop their sovereignty. The war ends if Russia leaves and respects Ukraine’s sovereignty.
Would you find it acceptable if Biden negotiated a deal where the Palestinian genocide would stop if half of Gaza fell under Israel’s total control? I certainly wouldn’t. You don’t give oppressors a reward.
