The Congressional Research Service published on 21 July 2026 a brief titled "Yemen: Conflict, Red Sea Security, and U.S. Policy" by Christopher M. Blanchard.
In March 2025, the Trump administration designated the Iranian-backed Houthis a Foreign Terrorist Organization. On March 15, 2025, U.S. forces began a military campaign against the Houthis which the administration said was intended to compel them to end attacks on international shipping in the Red Sea. The United States and the Houthis agreed to a truce in May 2025, which continues to hold.
