It might be a problem for Eastern Europe, but that's not certain. Can you tell me how long Ukraine has been an independent nation? Hmmmm? Was the U.S. threatened when the Ukraine was ruled by and/or a part of Russia, Austro-Hungarian Empire, Poland, Ottoman Empire, Cossacks, Tatars, Lithuanian Empire, or the Bulgars? How is Ukraine's defeat a problem for the U.S.?
