International Peace & Security

Our Goal

For more than three decades, MacArthur has supported efforts to broaden and strengthen the field of international peace and security. The Foundation has awarded more than 1,700 grants totaling more than $443 million in science, technology and security; weapons of mass destruction; and Asia security. General grantmaking in the International Peace and Security Program will come to a close in the next two years. The Foundation will now extend, and focus more deeply, on its longstanding support for reducing nuclear threats in its Nuclear Challenges big bet.
