Our record so far in the Pacific is:
- overwhelming win, sneak attack on Manila Bay, Philippines, Spanish American war (although it took some time to put down the Moro insurrection),
- bloody win, Japan,
- draw, Korea, and
- loss, Vietnam.
I can’t disagree with your list.
But, we were never defeated militarily in Vietnam. The US military didn’t lose; the US government did. I understand in the world of geopolitics that is a distinction without a difference.
We won Vietnam we.were too magnanimous in victory and allowed the Soviets to save face. Effectively we won Korea too in establishing a stable.though volatile border.
