The extraordinary pace of national security and counterterrorism law leaves teachers no choice but to tackle new developments as they occur. One feature that has made National Security Law and Counterterrorism Law so successful is that the authors have painstakingly updated their materials and coverage, not just through seven editions of the former and four editions of the latter, but in comprehensive annual supplements. The 2022-2023 Supplement -- with some 300 pages -- lets adopters of the casebooks teach from the headlines using a carefully curated compendium of cases, primary legislative and executive materials, case studies, and provocative notes and questions.

New to the 2022-2023 Supplement:

• State secrets: two 2022 Supreme Court decisions.
• Extended case study on the war in Ukraine.
• Law of war violations, including the crime of aggression, and cyberwarfare in Ukraine.
• Developments in targeting law, including over-the-horizon counterterrorism operations.
• Evolving U.S. cyber defense posture, including ransomware protocols.
• Heightened risks of nuclear war.
• Criminal and civil liability for violent domestic extremism.
• Case study on liability of Jan. 6, 2021 Capitol rioters.
• Analysis of CIA bulk data collection affecting Americans.
• Impact of coercive interrogation on Guantánamo military commission proceedings.
• Jan. 6 House Committee access to Trump presidential records.

These new materials are combined with updated coverage in the previous Supplement of the U.S.-Mexico border wall, emergencies, and related issues; extraterritoriality and cross-border shootings; legal issues arising from the COVID-19 pandemic; the domestic use of the military in protests, elections, and public health emergencies; and much more.
