Meanwhile, on both Russian and Ukrainian social media if you've spent the last few years under a rock and have no idea who these people are, Arkamia and Umarov are very important Ukrainian guys. Umerov was the head of the Ukrainian delegation at the recent tripartite peace talks that just concluded in Abu Dhabi. Vladimir Medinsky, an aide to President Putin, headed the Russian delegation, and Kirill Dmitriev was chosen by President Putin to be the negotiator with the Trump administration regarding the Russian-Ukrainian conflict.
(I didn't do that, I just translated it, but I must add that Amerov is a Crimean Tatar, not an Uzbek, although he was indeed born in Samarkand, not that it makes a difference in the grand scheme of things, especially considering that all these men were born and raised in the same country, the Soviet Union, and have the exact same green birth certificates with CCCP on the front cover).
