The Knesset, Israel's unicameral parliament, operates through a system of permanent and special committees that handle legislative oversight, policy review, and investigations. There are 12 permanent committees covering areas such as foreign affairs, defense, finance, education, and health. Committees deliberate on bills, summon officials for hearings, and conduct inquiries. The Foreign Affairs and Defense Committee is particularly influential in national security matters, often involving expert testimonies on threats and policy, including testimony from experts like Kuperwasser on security threats.
