The Assad dynasty, which has ruled the most strategic chunk of land in the Arab world for more than 40 years, may now face insurmountable odds. The three fundamental rules in a dictator's playbook of power have changed over the past two weeks.
Although modern autocrats rarely rally a majority, my experience is that they need at least 30 percent support at home to survive serious opposition challenges. They also need powerful foreign allies to prevent international isolation or invasion. And they also need to prevent viable, credible, or recognized alternatives to their leadership so they remain the only source of order.
