international strafferet
The body of law governing crimes that cross national borders or occur outside a single nation's territory. In U.S. federal law, this includes terrorism, piracy, human trafficking, torture, and other transnational offenses prosecuted under specific statutes rather than a unified international criminal code.

Definition
International criminal law refers to federal crimes involving cross-border elements or conduct occurring primarily outside the United States. Unlike domestic criminal law, which applies to offenses within U.S. territory, international criminal law addresses transnational offenses that impact national security, international relations, or involve multiple jurisdictions. The term itself is not a discrete legal category in U.S. federal statutes but rather describes a collection of specific criminal provisions enacted to address crimes with international dimensions.
The most clearly defined example in U.S. law is international terrorism, codified in 18 U.S.C. § 2331(1). This statute defines international terrorism as activities that involve violent acts or acts dangerous to human life that would be criminal under U.S. or state law, appear intended to intimidate or coerce a civilian population or influence government policy through intimidation or coercion, and occur primarily outside U.S. territorial jurisdiction or transcend national boundaries. This definition provides the foundation for prosecuting terrorism-related offenses with international components.
Beyond terrorism, international criminal law encompasses various transnational crimes addressed by specific federal statutes. These include maritime piracy under 18 U.S.C. § 1651, human trafficking under 18 U.S.C. § 1590-1594, torture committed outside the United States under 18 U.S.C. § 2340A, and crimes against internationally protected persons under 18 U.S.C. § 1116. Each statute establishes jurisdiction, elements, and penalties for offenses that either occur abroad or involve conduct crossing international borders.
In true crime contexts, international criminal law often describes high-profile cases involving terrorists, international fugitives, cross-border kidnappings, or organized crime networks operating across multiple countries. While journalists may use the term broadly, prosecutors rely on specific statutory authorities to establish federal jurisdiction over these offenses. The practical application requires demonstrating that the crime falls within the precise parameters of the applicable federal statute, including any required international nexus or extraterritorial conduct.
