Why did many civil rights leaders oppose president lyndon johnson on the vietnam war?

Many Civil Rights leaders opposed President Lyndon Johnson on the Vietnam War because they objected to the segregation in the U.S. military.

Opposition to United States involvement in the Vietnam War initiated with a series of demonstrations in 1964 in opposition to the escalating role of the U.S. military in the Vietnam War.

Lyndon Baines Johnson served as the 36th president of the United States from 1963 to 1969.

Johnson increased American involvement in the Vietnam War. In 1964, Congress passed the Gulf of Tonkin Resolution, granting Johnson the power to use military force in Southeast Asia without having to ask for an official declaration of war.
