In the turbulent annals of the Arab Spring, last weekend’s ceremony in Yemen was so quiet it was barely noticed. But it marked the transfer of power from an aging autocrat who had ruled for 34 years to a new leader who’s saying the right things about reform.

This was a stage-managed change of regime, and one that left some loose ends and unresolved questions. It was a product of backroom dealing and regional realpolitik. But in its very lack of visibility, the Yemen handover offered a counterpoint to the violent and still-uncertain transitions in Egypt, Libya and Syria.

So how did the Yemen story unfold, and what are its lessons as the U.S. struggles to cope with the other Arab revolutions? Every story in the Arab Spring is different, and there isn’t a “Yemen model” that can easily be replicated, but some interesting approaches include:

Working with regional proxies: The transition was brokered by the Gulf Cooperation Council. Yemen’s wealthy neighbors, Saudi Arabia and the United Arab Emirates, massaged and bankrolled the process, which culminated in an agreement last November that President Ali Abdullah Saleh would go. The GCC has often been a feeble talk shop in the past, but under Bahraini Secretary-General Abdul Latif al-Zayani, the organization is finding its voice. The Arab League has undergone similar transformation, from dictators’ friend to change agent.

Fighting terror without sending troops: Al-Qaeda’s potent presence in Yemen made the country a priority, and the U.S. several years ago began mobilizing resistance to Al-Qaeda forces in the south. The effort was coordinated by White House counterterrorism chief John Brennan, but it involved U.S. Central Command commanders, State Department diplomats and CIA officers. The U.S. often gives lip service to the “interagency process” while the military does the work, but in Yemen there actually was an aggressive joint strategy without “boots on the ground.”

Playing tribal politics: As with many Arab countries, Yemen’s state structure is loosely overlaid on powerful tribes. The U.S. has often botched this tribal factor, but it did better in Yemen – understanding Saleh’s tribal roots as well as those of dissident military officers. The big tribal confederations were convinced to align against Al-Qaeda. The Yemenis are now discussing a federal system that would ease the historical tensions between north and south.

Finding the right front man: To succeed Saleh, the U.S. and its allies tapped the longtime vice president, Abed Rabbo Mansour Hadi. An ex-military officer, he understood that the corrupt Yemeni system needed reform. Hadi was elected president last week in a one-man race that gave a veneer of democratic transition. He has promised to hold a referendum within 18 months on a new Constitution.

Reforming the military: In Yemen, as in many other countries, the military is corrupted because soldiers are paid through division commanders who skim money and undermine morale. The U.S. is encouraging Hadi to pay troops directly. Reform is needed, too, in the two security services headed by Saleh’s son Ahmad and his nephew Yahya. Because the U.S. relies on these groups against Al-Qaeda, it hopes to finesse change over the next several years. But if it waits too long, it will seem to be coddling the Saleh family.

Reaching out to the opposition: The U.S. was caught flat-footed in Egypt and Libya because it lacked good contacts with the opposition. U.S. Ambassador Gerald Feierstein and his colleagues in Sanaa have done better, meeting regularly with civil society groups and dissidents. Protesters say they plan to remain camped in “Change Square,” even with Saleh gone, which will test the diplomats’ patience.

The challenge in Yemen is getting closure on transition. As we’ve seen in Egypt, protest can become a way of life, to the point of threatening gains the opposition fought to achieve. The U.S. wants to gradually ease Saleh’s relatives from their leadership of the security forces, and moving to a more professional military.

“This revolution has been stabbed in the back,” Khaled al-Anesi, one of the protest leaders, complained to The Washington Post’s Sudarsan Raghavan. Hopefully, Hadi will deliver enough on reform to ease this sense of betrayal. The fact that Yemen is so poor and remote is an unlikely source of leverage for the U.S. and its allies. Curbing graft and spreading the wealth in this faraway state is the best strategy for getting “buy-in” for the Arab Spring’s quiet revolution.
