Stalin ym”s suffered a stroke on Purim (and died four days later) after having all but signed an order to exile all of the Jews to Siberia and do away with them.
There is an also an interesting story regarding the Nuremberg trials. In the parasha of the aseret bnei Haman (after Esther asks “the king” on today and tomorrow) there are three letters written very small:?, ? and ?. In ??? twelve Nazi war criminals ym”s were sentenced to hang (despite the fact that military executions were usually by firing squad). One, the efffeminate Hermann Goerring ym”s committed suicide in his cell (= Haman’s daughter?) and the other Martin Bormann ym”s was not present (unknown to them at the time he had also committed suicide in the bunker). When Julius Steicher ym”s mounted the gallows his last words were “today is Purim” although actually it was Heshvan.
