How did Washington become the best friend of the Muslim Brotherhood in Egypt, even as President Mohamed Morsi was asserting dictatorial powers and his followers were beating up secular liberals in the streets of Cairo? It’s a question many Arabs ask these days, and it deserves an answer. Morsi and his Brotherhood followers are on a power trip after decades of isolation and persecution. You could see that newfound status when Morsi visited the United Nations in September and even more so during the diplomacy that led to last month’s cease-fire in Gaza, brokered by Morsi and Secretary of State Hillary Clinton. The Brotherhood leaders had gone from outcasts to superstars, and they were basking in the attention.
