How did the U.S respond to the French defeat at Bien Dien Phu?

The U.S. response to the French defeat at Dien Bien Phu in 1954 was characterized by increased support for the anti-communist government in South Vietnam. Following the French withdrawal, the U.S. escalated its military and financial assistance to the South Vietnamese regime, believing that a communist takeover of Vietnam would lead to a domino effect in Southeast Asia. This set the stage for deeper American involvement in Vietnam, culminating in the deployment of combat troops in the following years.
