The alliance is only as strong as those willing to defend it.
We bring students, citizens, and professionals together to strengthen America's commitment to NATO and the transatlantic alliance.
Our mission
NATO is not an abstraction. It is the security architecture that connects American power to a free and stable Europe.
Defend NATO closes the distance between foreign policy and public life—from campus conversations to civic engagement and professional networks.
