The juiciest story behind the Middle East uprisings doesn’t concern Col. Muammar el-Qaddafi’s “voluptuous” Ukrainian nurse or C.I.A. bags of cash. Rather, it’s the tale of how a nonviolent revolutionary strategy crafted by Serbian students and an octogenarian American scholar came to challenge dictators in Egypt, Tunisia, Bahrain and many other countries.

This “uprising in a bottle” blueprint was developed by the Serbian youth movement, Otpor, to overthrow Slobodan Milosevic in 2000. One of Otpor’s insights was that the most effective weapon against dictators isn’t bombs or fiery speeches. It’s mockery. Otpor activists once put Milosevic’s picture on a barrel that they rolled down the street, inviting people to hit it with a bat.

Otpor’s strategy mirrors one promoted by a rumpled Boston academic named Gene Sharp, who is little known in America but inspires tremors among dictators abroad. Sharp’s guide to toppling despots has been translated into 34 languages so far and was widely circulated in Egypt last year in Arabic.

After Otpor toppled Milosevic, it began to hold seminars for pro-democracy activists from other parts of the world, including many from the Middle East.
