I'd say Korea counts as a US win or stalemate, but Vietnam ended with the US achieving none of its objectives, having wasted tons of lives and leaving in a humiliating fashion. Is it so weird to call that a defeat? In that case it's 50 years, given that Afghanistan ended in '21 in similar fashion.

Are you just taking issue with 70 years being hyperbole? If not, I have to say this idea that the US didn't lose a lot starting with Vietnam is weird. In fact, it seems like exactly the kind of delusional self-talk among the leadership that would lead to such situations reoccurring. I mean, suppose I get in a fistfight and get knocked down then don't get up. Can I really say I chose not to get up because I didn't want to hurt the guy too badly and I therefore didn't lose? Even if it's true, it just means I lost on purpose.
