It is possible that Putin thought the US would just let him take the whole country, so maybe he’ll be more willing to negotiate in good faith if he thinks the war will be much harder for him after all.

From Putin's perspective, he rules Russia with an iron fist.

So if he withdraws Russian troops from Ukraine, it is a signal showing his people that he is weak.

Putin knows he cannot allow that to happen.

Putin will continue the war until he conquers Ukraine.

Or continuing to fight the war of attrition. Even if it takes 10 years. Because that will keep him in power.

And you do not think that is exactly the same with NATO/DC/London/Trump or any other US President?
They have the same precise motivation.
