No , this decision came later during his presidency .
Army General William Westmoreland, who was the supreme commmander of all U.S. forces in Vietnam, asked Johnson in 1965 for more troops. This widened the war and the first major battle in Vietnam was the Battle of Ia Drang in the Pleiku Province of South Vietnam.
The two incidents (one actual sea battle, and one questionable sea battle) allowed President Johnson (LBJ) to transition the Vietnam War from a guerrilla war into a conventional open war against Hanoi (Capital of North Vietnam).
American withdrew
The easy and often repeated belief. US troops had been in RVN (Republic of South Vietnam) before Johnson (LBJ) was president; before his former boss JFK (Kennedy) was president. US servicemen were being killed in battle in South Vietnam long before LBJ took office in Washington. The Johnson administration commenced open war (via the Tonkin Gulf Resolution) with North Vietnam in August 1964. No other US president prior to LBJ conducted open hostilities with North Vietnam. Open hostilities=Open aerial bombing/bombing campaigns (Operation Rolling Thunder, etc.).

The longest war against another recognized government was the Vietnam War which took place from 1955 (President Eisenhower's administration) through 1975 (President Ford's administration).
Separate war from the American Vietnam War.
Most people accept the spread of communism as the prime cause of the Vietnam War, a battle of the cold war.
Abraham Lincoln was president for the entire duration of the American Civil War.
Johnson was unwillingly caught up in the hot battle (Vietnam War) of the Cold War. Johnson was the US's only Presidential Administration to be destroyed by the war. He went on nation wide television and flat out said he would not run for president again, and would NOT ACCEPT nomination for the presidency of the United States. He was truly fed-up with the war.
It authorized the president to send troops into battle
it caused president Johnson to send more troop to Vietnam
