You should take a closer look at the Neo Nazi factor. They have consolidated their power and again, are marching with impunity, in celebration of a massacre. The Azov Regiment isn't the only one which is Neo Nazi in the Ukrainian military. Subsequently they control local police, State/National Police and have refused to give any legitimacy to the Minsk Accord, which they agreed to, as they are hailed as heroes for fighting in Donbass. Now how do you think Russia should have dealt with the newly recognized republics where the President of Ukraine declared that no more talks and the people there begged Russia, as its ally, to help!? The Azov Regiment are directly responsible for the violent coup of 2014, they are responsible for breaking their very own cease fire agreement twice, there's documented war crimes on their hands and donbas regiment, and they are still the dominant power in enforcement and other spheres of society, which is why they can march with impunity, celebrating an atrocity in Odessa every year on that  day. Zellenzkyy also abandoned his own soldiers, he denounced 69 soldiers on Snake Island as he lied about the 13 he honored with heroism medals out of the 82 man garrison, all of whom are fine and surrendered peacefully. Then he ordered all men in the country to stay and fight, holding them prisoners, and the Azov Regiment are reported as firing on those that tried to flee. The Ukrainian media was silent when the Right Sector attacked, chased, and cornered 39 Ukrainians in Odessa before trapping them and burning them alive. They were silent in the face of those that celebrated that, and Zellenzkyy has banned the two opposing media outlets, while he imprisoned his political rival and opponents as he signed off on Russophobic legislation banning Russian from public places. He wanted no peace, no talks, and his culpability is undeniable in this situation. As for the Russian demands I'm sure you aren't suggesting that you haven't any idea what those are, because that would only indicate how uninformed you are on a topic you're debating, so in lieu of not burdening myself with fetching the concerns and demands of Russia for you I much rather remark that Russia's demands and concerns aren't unreasonable by any means.
