On February 28th, the United States and Israel launched Operation Epic Fury, a large-scale campaign targeting Iran’s national leadership, military forces, and intelligence networks. Iranian retaliatory strikes against Israel, U.S. military bases, and regional partners soon followed. President Trump indicated the operation could continue for weeks or longer as the United States seeks to destroy Iran’s missile and nuclear infrastructure, naval assets, and proxy forces.

The conflict carries significant implications for U.S. strategic forces. What has defined the campaign thus far—and what indicators should we be watching for next? What does a prolonged campaign mean for U.S. munitions inventories, missile defense capacity, and force readiness? How might the operation affect deterrence dynamics and adversary perceptions of U.S. resolve? And what are the broader regional and global risks if the conflict expands? To discuss these questions and more, please join the CSIS Defense and Security Department’s HTK Series for a conversation featuring Heather Williams, director of the CSIS Project on Nuclear Issues, Tom Karako, director of the CSIS Missile Defense Project, and Kari Bingen, director of the CSIS Aerospace Security Project.
