The Donroe Doctrine: Implications for the U.S. and the World
In-person, Members-only
Thursday, March 5, 2026 | 6:30 PM – 8:30 PM ET
The 2025 National Security Strategy (NSS) and 2026 National Defense Strategy (NDS) promised a hemisphere first pivot, reasserting the Monroe Doctrine to secure America’s own backyard. However, the sudden escalation of war with Iran and the resulting regional instability have thrown these strategies into immediate contradiction. While the Trump corollary calls for a focus on narco-terrorists and domestic borders, the U.S. military finds itself once again pulled into a high-intensity conflict in the Middle East and managing multiple leadership changes. Is this a temporary deviation from Donroe doctrine and what would such a deviation mean for the Western Hemisphere? What will the U.S. strategy be if global crisis breaks out in other parts of the world such as South China Sea?
Join us on Thursday, March 5 from 6:30 to 8:30 PM ET for an in-person discussion with Colonel Zeb Beasley, a U.S. Marine Corps officer and current Military Fellow at the Council on Foreign Relations, to explore the reorientation of U.S. power and its implications for global security.
