Eisenhower took a political risk. He was blasted by his Democratic rival, Adlai Stevenson, who charged on Nov. 1 that if the U.S. had acted more forcefully to support Israel, it might have avoided war. But Ike prevailed, winning re-election, forcing the attackers to withdraw from the canal, and enunciating a strategy for U.S.-led security in the region that came to be known as the "Eisenhower Doctrine." How does this story apply to modern-day Israel and America -- especially for an Obama administration that, while committed to preventing Iran from obtaining nuclear weapons, devoutly hopes to avoid military action? The parallels are impossible to draw precisely, but it matters that the cautious and fiercely independent Eisenhower is a role model for the prospective future defense secretary.
