Which act regulates the export of defense articles and services?

The Arms Export Control Act of 1968 is the legislation that specifically regulates the export of defense articles and services. This Act establishes the framework for controlling the export of military-related technologies and goods to ensure they are not misused or proliferated in ways that could threaten U.S. national security or foreign policy interests. Under this Act, the president is granted the authority to control the export of defense articles and services and to regulate the transfer of military equipment to foreign entities.

While other acts do involve aspects of trade and military sales, they do not specifically focus on regulating defense articles and services in the same comprehensive way as the Arms Export Control Act. For example, the Export Administration Act primarily concerns dual-use commodities and technology that have both civilian and military applications, rather than focusing solely on defense items. The International Traffic in Arms Regulations (ITAR) is a set of regulations that implements the Arms Export Control Act but does not itself constitute the federal law regarding export controls. The Foreign Military Sales Act relates to the sale of military equipment to foreign governments but is not the primary act that governs the export of defense articles.

Thus, the Arms Export Control Act provides the foundational legal authority for the export of defense items, making it the correct answer in this context
