Let's avoid creating a bunch of trash and mutilated human flesh in Ukraine.
My solution to this problem?
Send a Ukrainian to the ISS, (International Space Station).
There, the Ukrainian and Russian Astronauts can engage in fisticuffs, or arm wrestle, or play a game of "Killer Chess".
Winner of the contest gets to determine what happens in Ukraine, and a BUNCH of lives and equipment don't get wasted stupidly.
