International efforts to find a political solution to the conflict in Syria began early on in the war. The Arab League was the first body to attempt to mediate, starting in late 2012, but these efforts faltered due to the refusal of the regime –emboldened by the political support of Russia and China– to make a single concession, despite being on the back foot militarily. In 2015, new international efforts were launched to resolve the crisis. The U.S. and Russia reached an agreement over the formulation of United Nations Security Council Resolution 2254, which became the basis of UN-led negotiations between the opposition and the regime, including discussions on constitutional reform that began in 2019. However, more than a decade into the conflict, a political solution still appears distant, and is now closely linked to the fate of the foreign forces present in the country. The regime is no longer solely responsible for obstructing a solution. The presence on the ground of its allies, Russia and Iran, adds additional obstacles. It is no longer possible to formulate a peace deal without addressing the security concerns and various interests of foreign forces in Syria.
