This brief examines the national challenges related to deploying and scaling infrastructure to transport CO₂ from capture sites to storage or utilization sites at a scale consistent with achieving net-zero by 2050.

From July 11-12, 2023, NATO leaders gathered in Vilnius, Lithuania for one of the most significant NATO summits in history. This timely brief by Eric Rosenbach, Grace Jones, and Olivia Leiwant serves as a background piece on Ukraine’s history with NATO, potential future pathways for accession, and the operational impact Ukraine’s NATO membership could have on the alliance. 

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. 

The U.S. should accept with humility its inability to fully eliminate terrorism. Specifically, U.S. policy must balance “ends, ways, and means;” establish clear and achievable objectives; adopt efficient, effective, and resource-sustainable strategies; ensure synchronization of diplomatic and military efforts; build alliances to share the burden of countering terrorism; and leverage cooperative mechanisms and regional partnerships to increase the capacity and willingness of regional states to defend their sovereignty and contribute to multinational coalitions against terrorism.  A balanced, integrated, and synchronized strategy encompassing defense, diplomacy, economic, and humanitarian assistance lines of effort should be cornerstone of a revamped foreign policy in the coming decades.

By investing in the public and private sector research and development in this space, and by fostering a community of researchers, entrepreneurs, and investors literate in CO2 capture opportunities, the United States can be the leader of this new economic sector. It is essential for the Nation to build a vibrant and sustained research and development community spanning the public sector, academic and research domains, and for-profit companies, ensuring world leadership in this new technological domain.

The fields of automation and artificial intelligence are broad, having applications in diplomatic, informational, military, and economic activities. Within this realm, lethal autonomous weapon systems (LAWS) are a new enabler for achieving political ends through the application of the military instrument of power. As the world is past the point of considering whether robots should be used in war, the goal of the discussion herein is to examine how autonomous systems can be used ethically. This article seeks explicitly to demonstrate that fielding and employment of lethal autonomous weapons systems can be done effectively and ethically by maximizing the advantages and minimizing the shortfalls of both technology and the human mind. 

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.

Security assistance has long been an important component of American statecraft. The foreign policies of successive administrations have focused on empowering US partners to confront their own security challenges, rather than solving them through American force alone. Today, US foreign and defense policy indicates an intent to work “by, with, and through” partner forces to achieve shared goals. However, the outsourcing of American security objectives comes with a host of potential risks to civilians living in conflict zones or fragile states. Fighting with or relying on local partners–whose interests, priorities, and capabilities may not necessarily align with those of the United States–can complicate or even degrade America’s ability to minimize civilian harm during military operations.

This Policy Analysis Exercise (PAE) examines the causes and consequences of civilian harm in security partnerships, and its implications for US foreign policy

At 70, NATO remains the single most important contributor to security, stability and peace in Europe and North America. NATO allies, however, are confronting daunting and complex challenges that are testing both their purpose and unity. NATO’s leaders need to act decisively in 2019 to meet these tests and heal the widening divisions within the Alliance before it is too late.
