Three decades ago, President Jimmy Carter urged another staunch American ally - the shah of Iran - to loosen his grip on power, only to see his autocratic regime replaced by the Islamic Republic. More recently, U.S.-supported elections have strengthened such groups as Hezbollah in Lebanon, Hamas in the Palestinian territories and anti-American radicals in Iran.
"Jimmy Carter will go down in American history as 'the president who lost Iran,'" the analyst Aluf Benn wrote in the daily Haaretz this week. "Barack Obama will be remembered as the president who 'lost' Turkey, Lebanon and Egypt, and during whose tenure America's alliances in the Middle East crumbled," Benn wrote.
Raphael Israeli, a professor emeritus of Middle Eastern Studies at the Hebrew University of Jerusalem, echoed a widely felt perception that before the unrest erupted, the Obama administration paid only lip service to the lack of human rights in Mubarak's authoritarian regime.
"If Obama were genuinely concerned with what is going on in Egypt, he should have made the same demands two years ago (when he addressed the Muslim world in Cairo) and eight years and 20 years ago. Mubarak didn't come to power yesterday."
"As long as there are no problems, the oppression works," Israeli said. "If the oppression doesn't work, suddenly it becomes urgent. That's unacceptable."
