The U.S.-Israel Strategic Partnership Act of 2014 is U.S. legislation that designates Israel as a major strategic partner of the United States, aiming to strengthen bilateral defense and security ties. It enhances military aid and cooperation with Israel, building on prior defense ties, and authorizes enhanced military cooperation including joint military exercises, prepositioning of U.S. equipment in Israel, intelligence sharing, and support for Israel's qualitative military edge through expedited arms transfers and funding for missile defense systems like Iron Dome. The act also promotes cooperation in cybersecurity, energy security, and counterterrorism, while encouraging regional stability in the Middle East. It was incorporated into the National Defense Authorization Act (NDAA) for Fiscal Year 2015, enhancing long-term U.S. commitment to Israel's security amid regional threats.
