which resolution allowed president johnson to increase us involment in vietnam

lyndon B Johnson, the 36th President of the U.S., helped to escalate American involvement in Vietnam by sending more troops to war. This stimulated an anti-war movement and his domestic policies failed.
Lyndon B Johnson supported expansion of US involvement, and later Richard M Nixon worked to pull troops OUT of Vietnam through "Peace with honor."

Eisenhower sent some American military adviser to Vietnam and so initiated US involvement there. Kennedy did more of the same, but the war did not really start for the US until Johnson took office.
Because they were too stupid to realize that South Vietnam was a lost cause.
