I don't think Iran is like Egypt except in being it's opposite in some ways. Egypt long had the heavy hand of Mubarak suppressing a well-entrenched and large Muslim Brotherhood element. In Iran there is no Sunni Muslim Brotherhood and instead of the authorities imposing a degree of artificial moderation on a naturally radical society as in Egypt, the Iranian government imposes an artificial radicalism on a naturally more moderate people.
If the West can finesse its way through this nuclear crisis without having to force the Iranian regime and people together through military action, that nation may yet resume its natural role as an asset to regional peace and stability as it was under the Shah.
And Egyptians are not so inclined towards democracy. Take note, Obama. Or perhaps that’s why he was so “helpful” over there.
