"The Arabs had lost Palestine, it was a catastrophe, a nakba, as it became known. Several hundred thousand Palestinians had to flee, within the country or into neighboring countries. Palestinians felt they were being made to atone for Europe’s sin of the Holocaust by sacrificing their own land. They took the keys to their houses with them and never gave up on the idea of returning home one day. But in 1967, during six days of war, the Arabs lost more land: Gaza, the West Bank, East Jerusalem, including the walled old city that is home to Al-Aqsa mosque, as well as Egypt’s Sinai and Syria’s Golan Heights. Jerusalem was under Jewish rule again for the first time in two millennia. Across the Arab and Muslim world, there was disbelief, shock, and tears. Arabs had put their faith in nationalism and in Egypt’s president, Gamal Abdel Nasser. Just a few years prior, in 1956, Nasser had emerged victorious from a war for control over Egypt’s Suez Canal, staring down not only the French and the British but also Israel. The charismatic nationalist had become a hero for millions across the Arab world. How could he have lost this time? Perhaps, some people thought, God had forsaken Muslims; perhaps a return to religion was the answer."
