Russia's 2022 invasion of Ukraine illuminated the long profound shadow of nuclear weapons over international security. Russia's nuclear threats have rightfully garnered significant attention because of the unfathomable lethality of nuclear weapons. However, the use of such weapons in Ukraine is only one way—albeit the gravest— that Russia could challenge the global nuclear order. Russia's influence extends deep into the very fabric of this order—a system to which it is inextricably bound by Moscow's position in cornerstone institutions such as the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA). From withdrawing from key treaties to stymieing resolutions critical of misconduct, Moscow has demonstrated its ability to challenge the legitimacy, relevance, and interpretations of numerous standards and principles espoused by the West.

2023 marked eighty years since the wartime adoption of the BRUSA Agreement between Great Britain and the United States. This 1943 document codified the growing relationship between U.S. and U.K. signals intelligence organizations and included policies governing the exchange of personnel and joint regulations for handling sensitive material. Security directives and protocols aligned operational processes between the democratic governments, setting new cooperative standards for nation-states battling authoritarian regimes.

Although Russia and Iran have converged around the overarching objective of strengthening the Assad regime, Moscow and Tehran's engagement in Syria illustrates a complex mosaic of overlapping interests, broader regional entanglements, and contending approaches to post-war reconstruction. Russia and Iran's visions on the future of Syria include diverging views on military reform and economic investment. However, these disagreements are unlikely to lead to a breakdown of the relationship. 

This report charts some of the major developments in northeastern Syria from the December 2018 withdrawal announcement up until the start of Operation Peace Spring on 9 October 2019. It describes and notes the significance of the bitter dispute between Ankara and Washington over a proposed "safe zone," analyses how the Syrian Democratic Forces (SDF) have sought to navigate the crisis and gauges the strength of the so‑called Islamic State (IS) in Syria. Providing this context enables this report to selectively incorporate more limited analysis on the latest and most pertinent developments in northeastern Syria at the time of this writing.

This paper argues that the impact of the eight-year war in Syria will reverberate across the region for years to come, and explores, in particular, four noteworthy legacies. First, it examines the series of interventions in Syria by regional and foreign powers (including Russia, Turkey, Iran, the United States, Saudi Arabia and the United Arab Emirates) that reconfigured the role of such powers across the region. Second, it reveals the emergence of two opposing alliances in the region, each comprising Arab states, regional Arab and non-Arab powers, global powers and local nonstate actors. These or similar alliances may well reappear in other Middle Eastern conflicts. Third, it analyses the striking number and variety of foreign forces that either directly fought in Syria or indirectly supported warring factions. Since 2012, these forces have included at least twenty states and major non-state players, alongside hundreds of smaller tribal, Islamist and secular rebel and pro-Assad groups. Finally, the paper suggests that the international community’s weak response to the untold war crimes on both sides, and its apparent de facto acceptance of Syrian President Bashar al-Assad’s incumbency, portend continuing regional authoritarian and violent political systems for the foreseeable future.
