Continuing this war will only result in Ukraine still being Ukraine. At least in the areas not yet genocidally erased by invading Russian Nazis.
The Russians are very pleased you and our deluded political class feel that way. It gives them the green light to take, at a minimum, everything east of the Dnieper river and Odessa.
You're a fool if you think anything can prevent that. Ukraine doesn't have the troops to stop the Russian military.
