The Iranian Election and the Revolution Test

Successful revolutions have three phases. First, a strategically located single or limited segment of society begins vocally to express resentment, asserting itself in the streets of a major city, usually the capital. This segment is joined by other segments in the city and by segments elsewhere as the demonstration spreads to other cities and becomes more assertive, disruptive and potentially violent. As resistance to the regime spreads, the regime deploys its military and security forces. These forces, drawn from resisting social segments and isolated from the rest of society, turn on the regime, and stop following the regime’s orders. This is what happened to the Shah of Iran in 1979; it is also what happened in Russia in 1917 or in Romania in 1989. More here:
