How would America be today if they had won Vietnam somehow? No

>Would it be appreciated and respected like WWII and Korea?

Doubtfully as much as WWII, probably on similar lines to Korea (though you couldn't really call Korea a victory considering the country was partitioned).

>Or would people still regret going over there because of the protests by hippies.

Hippies would probably still not approve, but more people would chalk it up as "we saved those Vietnamese from some brutal communist regime."

>Would the Veterans feel better if they had won?

Duh. Some would still be fucked from mental/physical injuries but in broad strokes of course soldiers prefer to be victors.
