Status of Forces Agreements (SOFA)

When the United States stations military forces in another country — as it does in more than 80 countries — a fundamental legal question arises: if a US service member commits a crime, which court has jurisdiction? The SOFA is the treaty instrument that answers this question. There is no single SOFA — each is individually negotiated and reflects the relative bargaining power, strategic relationship, and domestic political dynamics of the two countries involved. The NATO SOFA (1951) is the template agreement covering all 32 NATO members. Separate bilateral SOFAs govern US forces in Japan (under the US-Japan Security Treaty framework), South Korea, and dozens of other countries. Where no SOFA exists, US forces operate under whatever permissions the host nation grants, creating significant legal uncertainty.

The NATO SOFA's Article VII establishes a concurrent jurisdiction framework with primary rights allocation. For offenses that are crimes only under US law (e.g., purely military offenses like insubordination or going AWOL), the US retains exclusive jurisdiction. For offenses that are crimes only under host nation law, the host nation has exclusive jurisdiction. For offenses that violate both legal systems, jurisdiction is concurrent — but the SOFA allocates primary right: US forces have primary right in cases arising from official acts or offenses against US property or personnel; host nations have primary right in all other cases. This allocation has been heavily negotiated in bilateral agreements, with Japan and South Korea securing modifications giving their courts primary jurisdiction in more categories of serious crimes.

The practical result is that US service members accused of serious crimes — assault, rape, manslaughter, murder — against local nationals in Japan, South Korea, and other SOFA countries have historically been tried by US military courts rather than local courts. This has generated intense political resentment. The 1995 Okinawa rape case — in which three US servicemen abducted and assaulted a 12-year-old girl, were initially shielded from Japanese custody, and received relatively light sentences — triggered mass protests and a formal review of the US-Japan SOFA. The US agreed to give Japan custody of suspects in heinous crime cases before indictment, an important modification that has not eliminated the fundamental tension over jurisdictional primacy.
