The primary deterrence challenge facing the United States today is preventing aggression and escalation in limited conventional conflicts with a nuclear-armed adversary.
How long will the immigration agency leave this money on the table? Background As the primary federal agency responsible for legal immigration, U.S. Citizenship and Immigration Services (USCIS) is almost entirely funded by user fees rather than appropriations from Congress. In May 2020, USCIS claimed that, due to a lower volume of fee collections caused […]
This report uses data gathered from multilingual sources to explore China’s motivations behind its systematic ADIZ intrusions as well as the implications for Japanese, South Korean, Taiwanese, and U.S. forces operating in Northeast Asia.
The Trump administration is expected to unveil an executive action in the near future that would significantly restrict temporary (“nonimmigrant”) work visa categories. While there are multiple public data sets available from the Department of Homeland Security and the Department of State relevant to these visa categories, they are unfortunately not sufficient to answer these […]
The debate over whether North Korea could be deterred was eclipsed by the onset of negotiations in 2018. Yet, the last three years have been marked by rapid advancements in the regime’s military capabilities and apparent evolution in its military strategy, which now relies on the threat of preemptive attacks against allied conventional forces to […]
In 2018, Russia and China both tested an uncommon type of missile that flew a ballistic trajectory but could be launched from an aircraft. Air-launched ballistic missiles (ALBM) are just one curiosity at a time when many countries are rapidly expanding and upgrading their missile inventories, but the tests raised some understandable questions: Is this […]
The FAS International Study Group on North Korea Policy convened to develop a strategy toward a North Korea that will in all likelihood remain nuclear-armed and under the control of the Kim family for the next two decades. The composition of the group reflects a conviction that a sustainable and realistic strategy must draw on […]
The goal of this Task Force report is to offer findings and make recommendations regarding nonproliferation monitoring and verification in general; our observations are grounded in large part on the Task Force’s continued attention to nonproliferation developments such as the Joint Comprehensive Plan of Action (JCPOA) between the P5+1 and Iran, nuclear developments in North […]
A so-called loophole might allow a non-nuclear weapon state (NNWS) to use a naval reactor program to acquire nuclear weapons by taking nuclear material outside of safeguards and then potentially diverting some of that material. Additionally, nuclear-armed states with nuclear-powered warships might use their naval reactor programs to justify keeping a substantial inventory of highly […]
This report examines the nuclear dynamics and implications for strategic relations in a world where four nuclear-armed states are developing strategic ballistic missile defenses (BMD). These states are the United States, Russia, China, and India. Each state appears to have the common rationale of wanting at least limited protection against ballistic missile attacks, and all […]
This special report is a result of the FAS U.S.-French Naval Nuclear Task Force and is focused on the life-of-the-ship reactors and role of accelerated testing on naval propulsion fuels and reactors. The report is written by Dr. George Moore.
This special report is a result of an FAS task force on French naval nuclear propulsion and explores France’s decision to switch from highly-enriched uranium (HEU) to low-enriched uranium (LEU). By detailing the French Navy’s choice to switch to LEU fuel, author Alain Tournyol du Clos — a lead architect of France’s nuclear propulsion program — explores […]
