After years of chaos, it appears that Iraq and Syria are gradually stabilizing. The government forces supported by the US and Russia respectively are restoring their control over the two countries, and the self-proclaimed Islamic State has lost virtually all of its territory.
Yet, this may just be an ephemeral peace. The social and economic foundations of the two states remain shaky at best, and many issues are still unsettled; notably the role of Sunni Arabs and the future of the Kurds.
Without a comprehensive action to solve such questions, peace in Iraq and Syria will not be achieved on a solid basis.
