So lets see the reasons they cite for these choices then
For Hitler 1938 "As German Chancellor, Hitler oversaw the unification of Germany with Austria and the Sudetenland in 1938, after the Anschluss and Munich Agreement respectively."
Hardly a harsh criticism
For Stalin 1939
" In 1939, Stalin was General Secretary of the Communist Party and de facto leader of the Soviet Union. He oversaw the signing of a non-aggression pact with Nazi Germany before invading eastern Poland."
Again hardly a criticism
IF this is true, why wasn't Osama Bin Laden Man of the year for 2001?
