US War Crimes Act — Domestic Prosecution for Geneva Convention Violations

The War Crimes Act of 1996 (18 U.S.C. § 2441) created federal criminal liability for US nationals and military personnel who commit 'grave breaches' of the Geneva Conventions. The statute was designed to fulfill the US obligation under Common Article 1 of the Geneva Conventions — to 'respect and ensure respect' for the laws of armed conflict. Originally covering only grave breaches, Congress expanded it in 1997 to cover all violations of Common Article 3 (protections for non-international conflict detainees).

The political history of the statute is fraught. After the Abu Ghraib prison abuse scandal (2004) and legal memos authorizing 'enhanced interrogation techniques,' the George W. Bush administration sought and obtained the Military Commissions Act of 2006, which retroactively narrowed the War Crimes Act to remove criminal liability for several techniques used by the CIA. Critics argued this retroactive narrowing was an admission of prior liability and an obstruction of accountability.

Despite its sweeping language — including the death penalty for violations causing death — the War Crimes Act has never resulted in a prosecution. The gap between statute and enforcement reflects the broader challenge of accountability in modern warfare: military justice systems handle most violations internally, and political will for federal War Crimes Act prosecutions of US personnel has been historically absent.
