Max Boot at the Council on Foreign Relations put it this way in the Los Angeles Times: “It is no coincidence that both Osama bin Laden and [al-Qaeda deputy Ayman al-] Zawahiri hailed from US-allied nations that repressed their own citizens. Both men were drawn to the conclusion that the way to free their homelands was to attack their rulers’ patron. It is reasonable to expect that a new generation of Islamists in Egypt, now being taught that the peaceful path to power is no longer open, will turn to violence and that, as long as Washington is seen on the side of the generals, some of their violence will be directed our way.”
Even if the Egyptian army faces the kind of full-blown Islamist insurgency that ripped through Algeria in the 1990s—which is unlikely, but possible—Cairo will still get all the help it needs from the Gulf, not because the Saudis oppose radical Islam, but because they view the Muslim Brotherhood as the biggest long-term threat to their rule.
The case for walking away from Egypt and dusting our hands off is sound.
