Rahm Emanuel with his brothers and his father, Benjamin, who admitted to the author that he had been a member of the Irgun, a terrorist gang headed by Menachem Begin.

Menachem Begin was a well-known terrorist who went on to become prime minister of Israel.

Begin had been a criminal in the Soviet Union (1940) before bringing his terror methods to Palestine.

Menachem Begin was the terrorist head of the Irgun when it bombed the King David Hotel in Jerusalem, killing nearly 100 people.  Rahm Emanuel's father was an active member of this terrorist gang at the time and probably was involved in this atrocity given the fact that he lived in Jerusalem at the time.
