The war began in 2014 after Nuland and the EU engineered a coup against the duly elected government of Ukraine. This spawned the separatist movement in the Donbas and the first Russian invasion that annexed Crimea. Obama/Biden did absolutely nothing in response save some meaningless sanctions.
Ukraine's isn't giving up, Putin needs to go home before he suffers more embarrassing defeats.
Putin is going nowhere. Russia shares a 1,400 mile border with Ukraine. The Russians consider Crimea as much a part of Russia as Moscow. Putin will use every weapon at his disposal to protect the territorial integrity of Russia.
Time to end this war. Prolonging it only causes more death and destruction, mostly to Ukraine. Paraphrasing something we used to say in Vietnam, we had to destroy Ukraine in order to save it.
