Egypt's liberal and secularist groups, long plagued by infighting and poor organization, say the coup that ousted the Islamist president, Mohammed Morsi, has given them a second wind and a fresh chance to unite.

For the second time in 2½ years, young liberal activists ignited a protest movement that provoked a military intervention. They again succeeded in forcing out a president and celebrated in Tahrir Square with fireworks, patriotic anthems — and promises of a better tomorrow.

But it was unclear whether anti-Islamist forces have developed a strategy that extends beyond a vague "road map" outlined by the head of the armed forces, Gen. Abdel-Fattah el-Sissi, as he announced Morsi's dismissal Wednesday night.
