What did president Johnson do in response to a Vietcong attack in Feb 1965?

In response to a Vietcong attack on US Military installations in February 1965, President Lyndon B. Johnson ordered a significant escalation of American military involvement in Vietnam. He authorized the bombing campaign known as Operation Rolling Thunder, aimed at targeting North Vietnam and the Vietcong. This marked a shift in US policy, transitioning from advisory support to active combat engagement in the Vietnam War.
