Yes, Kennedy sent advisors, in the early sixties.

Johnson was pres from 64 to 68 and did expand the war significantly, and under pressure from Bobby Kennedy among others who represented people who did not want to continue the war bowed out of the 68 presidential race.

bobby was on the way to winnning the democratic nomination when he was assassinated.

Nixon was elected on the bogus premise that he had a plan to get us out of Vietnam that was secret.

His secret was turned out to be to expand the war by bombing cambodia etc. He was pres and re elected in 72 only after George Wallace was assassinated (unsuccessfully) and taken out of the race.

We finally pulled out of Vietnam in I believe 73 and he resigned in disgrace in I believe 74, so to lay the war on anybody other than Nixon seems a little lame since he presided over six years of it, a year more than Johnson after being elected on the secret plan to get us out of it.
