Foundation for Defense of Democracies

The Foundation for Defense of Democracies (FDD) is a neoconservative non-profit think tank based in Washington, D.C., United States. It has also been described as a pro-Israel, anti-Iran lobby group due to its focus on Iran and opposition to the Joint Comprehensive Plan of Action.

FDD publishes research on foreign policy and security issues, focusing on subjects such as nuclear-non proliferation, cyber threats, sanctions, illicit finance, and policy surrounding China, Iran, Israel, North Korea, Russia, Turkey, and the war in Afghanistan.

In September 2019, FDD executives formed the 501(c)(4) organization FDD Action, which officially registered as a lobby under the Lobbying Disclosure Act of 1995 on 15 November 2019.
