The Libya Analysis team pere et fils write for Christian Science Monitor about the likely best case scenario for Syria -- Look to Yemen as model for Syria's transition after Bashar al-Assad: Recent history in Iraq and Libya shows that the departure of a tyrant can lead to a deterioration in stability and an increase in human suffering. In Syria, a Yemen-style transition (dictator forced into exile to be replaced by a transition figure) may be the best possible outcome.Since the European empires have been decolonized, brutal tyrants have arisen to hold together the most volatile remnants of empire – states that are not really nations. Iraq, Syria, and Libya are just a few examples of colonial amalgamations of different sectarian, ethnic, or regional groups.In the 20th century, the colonial overlords and then their post-colonial strongmen replacements kept their internal fissures in check by force. Understanding this history, UN-Arab League special envoy Kofi Annan is right to be wary of military intervention in Syria and to seek regional support for a political transition there. An ill-conceived international intervention to remove Assad – especially if it lacked regional support – could easily unleash a war of all against all.Looking to Yemen – which many have called a failed state – as a model for anything may seem counterintuitive. The country is fraught with internal strife, high rates of poverty, drought, drug abuse, and Islamist terrorism. But Annan and others have hinted that the recent process for political transition in Yemen is the one they hope to largely duplicate in Syria.A few tweaks to Annan’s proposals would improve its chances of success. First, the path to peace in Syria requires an “imposed non-military solution.” This would be a political transition driven by outside powers with broad international support.
