The result is a revolution that remains incomplete, with the coalition that formed in Tahrir Square splintering over different visions of a post-Mubarak future. But few dispute that the uprising launched on January 25 has changed an ancient nation in a fundamental way.  "I am optimistic about the future. We can't go back," said Lillian Wagdy, a photographer who was taking part in the protests. "The wall of fear has fallen, and the people will now demand their rights and stay on the streets."  And Fawaz Gerges, director of the Middle East Center at the London School of Economics, said Egyptians have undergone a "psychological rapture" since the revolution.  "The psychology of the citizen has changed," he said. "Millions of voiceless people have regained their voices ... It's changed the relationship between sons and fathers and fathers and daughters."  The protests lasted 18 days, growing despite clashes with police and pro-Mubarak gangs. The armed forces refused to intercede on Mubarak's behalf, and he handed over power to a council of generals on February 11.  The generals suspended Egypt's constitution and named a civilian caretaker government, but remain the final authority in Cairo. That's one of the things that rankles the protesters who have made camp in Tahrir Square since a fresh round of protests in June.  "For me to leave Tahrir, the ruling generals need to listen to our demands and take action to ensure them," said Mustafa Sadek, a 16-year-old high-school student taking part in the protests last week. "We also want a clear schedule, a path to elections and reform. We want a plan that lays out the future."  Rajia Omran, a lawyer and human rights activist, said the revolution "isn't going too bad." But she said patience will be needed for months or even years to come.  "It will take 5 to 10 years to evaluate the revolution," said Omran, whose group helped organize the first protests. "Nobody can evaluate it now. Any evaluation now is premature."
