I do see Zelensky's point.
Putin is like Hitler. You have to knock him out until his nose bleeds.
Agreeing to a ceasefire, Russia will simply rearm and attack Ukraine again later.
And Russia certainly knocked Hitler out! What ever possessed Hitler to think that he could have conquered the whole of Russia, we'll never know. Russia is vast, and there was no way that Germany was ever going to defeat Russia. When Hitler invaded Russia, Stalin destroyed bridges, destroyed crops to make it harder for the Germans to advance. He even had entire steel and munitions plants in the western part of the country, dismantled and shipped by rail to the east, where they were rebuilt, and put back into use.
