wrong so much wrong with your thinking
America First means defending our borders not being paranoid that every chicken sh*t dictator is going to invade us.
Arguing heroism versus cowardice is childish, really childish.
We capitulated in 1975. It would have been smarter to have capitulated in 1969. Are you going to argue the blood and treasure loses from 69 to
75 was worth it ?
Why 1969? Why not 1963 or 1964? We could have done it just by not providing advisers or equipment. I sometimes wonder what this country would be like had we not fought the Vietnam war.
We had no choice at all but to fight in Vietnam. That was where the Soviets and the Chinese chose to push their National Liberation War tactic (a sort of externally-supported civil war) and that particular battlefield was in the center of our SEATO allies and in a position to allow the Soviets command of the Straits of Malacca. You don't have to even have a globe in front of you to figure out how that would have affected Japan, South Korea, the Philippines, and even Australia.
Those of us with the patriotism and courage to do so fought ably for our country for over eight years. Low-intensity wars like Vietnam (and Afghanistan and Iraq) take time - decades even - if you're going to win. Your soulmates, the American Left ran a treasonous pro-enemy opposition movement masquerading as a "peace" movement (with the help of cowardly males here) that eventually gained control of Congress and that is what caused the end of our war.
In the end, there weren't anymore "National Liberation Wars" because the Sovs and the Chinese underestimated how much they would cost and were surprised that our young men were capable of what we did in Vietnam. To a very large extent, it was the vision of our courageous Americans combatants in Vietnam that cut back Soviet power and gave Reagan the leverage he needed to end the Cold War.
Cowardice won't protect us. The only thing between us and the vicious cruds out there are our brave military men and women and all the technological edge we can give them.
Aren't you at all embarrassed to even have young women, of all things, lining up to fight our enemies when you're willing to tell anyone who is willing to listen that you just want to hide out on your living room couch and pretend the cruds out there won't come for you?
One of the leaders of a nearby Southeast Asian country, I believe it was Thailand but I’m not sure, said after the war that the period from 1965 to 1975 allowed his country a chance to avoid turning red. This article by the New York Times no less discusses the overall situation:
