We couldn't really say how much are dead on Ukraine's side. Only the Russians has the time to count their dead mean since they have this war in control. Ukrainian dead were even left on the roadside to rot. And the infrastructures that are destroyed are in Ukraine. If they want their country to be still like remains as is which they can pick up the pieces and resume back to where they are before the war, they could just go on with the peacetalks. Putin still offer the peacetalks afaik.
If Zelensky has care for the country he should be accepting the peace talk that Putin is offering. Its been two months, no one is going to go to Ukraine for war. Regret always happen after things are over but they can stop it while its yet not too late. They may even given opportunities after. Heck Russia has more gas and oil to offer to Ukraine if they make business instead. They may even help rebuild the country.
I think you confused something. Ukraine count their dead men, few weeks ago Zelensky mentioned estimate numbers of dead and injured, but they reasons not to give frequent updates about it. While Russia really leaves their dead troops to rot in fields and to be eaten by wild dogs, despite that they're saying ''Svoikh Ne Brosaem''. And there is thousands of unclaimed dead soldiers are stored in Ukrainian morgues:

I am especially amused by your ability to diagnose Putin by his hand on the edge of the table, while Biden regularly shakes hands with the void.

I can't diagnose disease from photo, but do you think that Putin is looking OK in this photo? And where these long tables is gone? Wouldn't be surprised if it's another faked video. And it's also not often thing to see Shoigu wearing civilian clothes.
Biden is another story, but I don't like whataboutism.
But in general, the civilian infrastructure in Ukraine is now surprisingly in good condition.
Especially Mariupol.
You don't seem to understand this. Russia is not at war with Ukraine, this is a military special operation. If Russia had really declared war on Ukraine, it would have ended a month ago. There is no martial law in Russia, there is no mass mobilization, normal peaceful life is going on in all regions, with the exception of three regions bordering Ukraine, where a yellow level of terrorist threat has been declared. I do not know with whom Ukraine is fighting there, but Russia did not come to this war. And be glad it is.
I know that in Russia you're not allowed to use word war for this, but sorry, that's war. One country armoured invasion into another country is war. Yes, there is no martial law and mass mobilization in Russia, but these things happening in Ukraine is war. But Russia sometimes don't like call thing with real their names.
