Iran: The Regime Still Crumbles
What happens next will be determined by three factors: leadership, unity and momentum.
The opposition is most vulnerable on leadership. The big unanswered question is whether Mousavi, a distinctly uncharismatic politician, can lead the new opposition over the long term. He was an accidental leader of the reform movement, more the product of public sentiment than the creator of it. Without dynamic direction, the opposition may look elsewhere.
The regime is most vulnerable on unity. Many government employees, including civil servants and members of the military, have long grumbled about the strict theocracy. In 1997, a government poll found that 84 percent of the Revolutionary Guards, which include many young men merely fulfilling national service, voted for Mohammad Khatami, the first reform president.
Momentum may be the decisive factor. The regime will need to shift public attention to President Mahmoud Ahmadinejad's second-term agenda. Though Ahmadinejad blames the outside world for the protests, he may focus on regional or international goals to win the legitimacy that his presidency is unable to get at home.
For the opposition, the calendar of Shiite rites, Persian commemorations and revolutionary markers is rich with occasions to spark demonstrations. The opposition also has supporters in Iran's parliament who are likely to challenge Ahmadinejad's cabinet choices and economic proposals. Further arrests and future trials could also spark new tension. With each flash point, the regime's image is further tainted, its legitimacy undermined.
