grandfather fought with the German fascist scum

Well this is straight up false - in fact his grandfather fought in the red army against the Nazis, and lost his siblings AND father in the Holocaust.

"The president applauded someone introduced as a Ukrainian war hero, who was afterwards revealed to have been a nazi" does not retroactively legitimise the illegal Russian war of aggression.

Russia’s invasion of Ukraine, in clear violation of the United Nations Charter and international law, is aggravating geopolitical tensions and divisions, threatening regional stability, increasing the nuclear threat, and creating deep fissures in our increasingly multipolar world.

Nobody is arguing that the Nazi deserved any of the respect he was given, to the extent that it has become an international scandal that he was allowed in the building.

it is nullifying everything that the Russians created

This is the really revealing part of your imperialist rant. You have decided that Ukraine is a "russian creation" that intrinsically belongs to them, rather than a sovereign nation that has a right to self determination. This is despite the fact that Russia is a signatory to the Budapest Memorandum on Security Assurances, which obligates Russia not to use military force or economic coercion against Ukraine, except in self defense or otherwise in accordance with the Charter of the United Nations, in exchange for their giving up nuclear weapons.

Ukraine has not violated this agreement, nor been an aggressor against the Russian Federation.

As such, the Russo-Ukrainian war is an illegal war of aggression under international law, and the Russian Federation's occupation of Crimea and the Donbas is illegal.

Russians are not "evil". Putin, however, most certainly is, and he deserves to stand trial in front of the international criminal court.

Just leave Ukraine and the war ends. It's that fucking easy. Get out.
