Would it have been worth it to use low-yield tactical nuclear weapons during Vietnam War?

Yes. We were fighting a war our leaders were unwilling to win. One nuke between N Vietnam and China would have done the trick. Our enemies learned we weren't willing to use our own weapons. We still aren't.

You were fighting a war which a certain activist part (around 20-30%) wanted to lose. That same quisling part of the population now has the power and talks, among themselves, about extermination camps.
