Eighteen days of protest ended 30 years of one-man rule by Egyptian President Hosni Mubarak. While the demonstrations had been mounting in intensity and reflected deep-seated grievances that had been building over decades, his decision Friday to step down was never certain. As the country enters a new era, Egypt's future is unclear. The army is now in charge, and its commitment to democracy is uncertain. Friends of Egypt and supporters of democracy should do all they can to push the nation toward a stable and sustainable democracy.

Protests began Jan. 25, 10 days after demonstrations forced the resignation of Tunisian President Zine al-Abidine Ben Ali. Egyptians were complaining about high inflation, high unemployment and government repression. First, Mr. Mubarak tried the time-tested response — he sent riot police to break up the protests, but that tactic proved ineffective. Then the government took the country offline, disconnecting from the Internet in an attempt to silence and disorganize the protesters.

That too failed. In a last-gasp effort, loyalists unleashed a vicious assault on the protesters, with plainclothes security forces attacking demonstrators. Throughout this process, Mr. Mubarak offered one concession after another to the demonstrators in hope of placating the protesters. Rather than appeasing them, his moves only encouraged more demands.
