Bill Kristol in the New York Times:
"When President Kennedy spoke to a huge crowd in front of West Berlin’s city hall in June 1963, victory in the cold war seemed a distant hope. The Soviets had crushed the East German uprising of 1953 and the Hungarian rebellion of 1956. Castro had taken power in 1959. The Berlin Wall had gone up in 1961. The Cuban Missile Crisis had brought the world to the brink of war less than a year before. There were many, in Europe and elsewhere, who wanted to find a way out of the struggle. Speaking on behalf of “the world of freedom,” Kennedy challenged the anti-anti-Communists and the peaceniks. He chastised the “many people in the world who really don’t understand, or say they don’t, what is the great issue between the free world and the Communist world.” He rebuked those “who say in Europe and elsewhere we can work with the Communists.” To all of them, Kennedy memorably said: “Let them come to Berlin.” Perhaps Obama — with the Victory Column at his back — will also challenge those who think it impossible to imagine victory today. Perhaps Obama will also warn of the temptation of assuming we can somehow avoid confronting the terrorists and jihadists, and those who support them."
