How many U.S. Presidents were involved in the Vietnam War?

Jew for Yeshua, sure, I read that too, but US troops weren't involved in fighting until Kennedy or Johnson. My main point is that the question is dumb to count "involvement" as meaning there was a war going on that we weren't involved in!

Photos were very misleading.....my impression was that the question was aimed at those pictured .

Also, including Truman is just plain wrong, as the war that eventually became the Vietnam War started during Eisenhower. Bad question and wrong answer, nice double bad.

Poorly written question. If you want to ask how many US Presidents terms did the Vietnamese Civil War overlap with, then ask that. The "Vietnam War" meaning American military active participation in the war doesn't start til early 60s under Kennedy
