From an opinion piece on politico.com by Tom Malinowski headlined “How to End the War in Ukraine—Even If Vladimir Putin Wants to Keep Fighting”:

“Ukraine will never be a victory for Russia — never,” President Joe Biden said in a speech in Poland this year, and rightly so. For the war in Ukraine to end on terms consistent with American interests and ideals, Ukraine must be seen to have won, and Russia’s invasion must go down in history as a decisive failure, enough to deter other authoritarian powers from launching similar wars of aggression in the future.
