My top 5 for pure evil:
Nazi Germany
Soviet Union (Stalin-era)
Imperial Japan (1931-1945)
Khmer Rouge
DPR Korea
(Dis)-honorable Mention:
PR China (Mao-era)
Edit: Added DPRK to list and moved Maoist China to DM
@Parmenion I hate to tell you, but "Shek" is not his surname...it's Chiang.
Don't worry too much about it though.
Harry Truman reportedly did the same thing😎
