Ask him about Communist rule in Ukraine, when Stalin banned the Ukrainian language, literature and culture from being taught or practiced [along with the Ukrainian diet], while exploiting the wheat crop, the Donbass and their other resources for the Soviet Union [which MILITAARILY occupied Ukraine], about Soviet policy in Outer Mongolia, denying the mention of Chinnghis Quan, and any study of Mongol history, and about the attempts to culturally annihilate the Volga Germans, Krim Tartars, Kalmucks, and various other ethnic minorities, while exploiting their slave labor in the Gulag [Soviet Russia was a largely slave driven economy]..
Or you might ask him about Tibet. You know. That place where the Chinese militarily occupied it,colonize it, deny the locals their desired choice as spiritual leader, all based on the premise that Tibet is part of China because it was once part of the Ming Empire.
