In response to a Vietcong attack in February 1965, President Johnson escalated U.S. involvement in the Vietnam War. Here's a breakdown of his actions:

1. Operation Rolling Thunder: Johnson initiated a sustained bombing campaign against North Vietnam to weaken the Vietcong and their supporters.

2. Sending Troops: He authorized the deployment of ground troops to Vietnam to support South Vietnamese forces in combating the Vietcong.

3. Gulf of Tonkin Resolution: Following an alleged attack on U.S. ships in the Gulf of Tonkin, Johnson used this incident to gain broader congressional support for military action in Vietnam.

4. Increased Military Aid: Johnson ramped up military aid to South Vietnam to bolster their defenses against the Vietcong.
