Some years ago, I witnessed a televised discussion between assorted Russian and American college students on World War II. The Russians were lecturing "ignorant" Americans on how much more the Russians had to do with defeating Hitler's war machine than the Americans.
Finally, one American from Brigham Young University told them about the infamous pact which made the entire war possible. The Russians were dumbfounded and refused to believe it. The same young man told them to look up the Nuremberg trial of Ribbentrop, who ended up being the first one to be hanged for his role in starting the war.
Another piece of Nuremburg trivia is that Herman Goering was actually the first scheduled to be hanged but he cheated the hangman by suicide just hours earlier.
So Ribbentrop got the honor instead.
