Module 2. This second module concerning Homeland Security in Israel focuses on the organizational and operational environments that frame Israeli counterterrorism strategies. Contrary to the United States, Israel has only a small number of agencies that are actively engaged in various aspects of counterterrorism intelligence-gathering, combat, and law enforcement. The primary agencies and organizations within Israel are the Israel Police, the Israel Security Agency (ISA), the Israel Defense Force (IDF), and the Institute for Intelligence and Special Duties. We are also provided with a summary of Israel’s governmental organization, and a comparative analysis of the United States and Israeli systems of government and law enforcement.
