As Nazi Germany's Foreign Minister, Ribbentrop shaped the diplomatic architecture that enabled the war — most consequentially through the Molotov–Ribbentrop Pact, which neutralized the Soviet threat long enough for Germany to move westward. His role was less that of an ideologue than a facilitator: leveraging social connections and foreign exposure to open doors that other senior Nazis could not. The Nuremberg tribunal found him guilty on all four counts, including crimes against peace and war crimes, and he was the first of the major defendants to be hanged.
