You have to remember that Johnson had watched Harry Truman in the Korean War when he never really got the Congress on board, and the war was fought in Korea without congressional sanction. LBJ learned from everything; he was a great observer of the presidency. Months before, he had Bill Bundy draw up a resolution that would support us in Vietnam; after Tonkin he had it presented to the Hill. It all stemmed from his view that Truman made an error in not going to Congress.
