No. American and allied troops fought in the Vietnam conflict. Our strategy evolved in the Cold War and proxy wars. A proxy war is fought only with fiscal, humanitarian, and arms support.
For example, we destroyed Afghanistan in the 80’s by supporting the mujahideen fighting against the Soviet Union: a proxy war. Unable to communicate what’s been done, they resorted to extreme violence in September, 2001. So, we fucked 'em all the war back to 17th century religious persecution.
I’m a born American. I love so much about this country at the roots of the land and people I meet in it. But, it’s totally fucking rotten at the top and we refuse to admit it. If we did then we’d have to do something about it. Then, it quickly becomes obvious that voting isn’t going to do jack shit. That’s scary as fuck.
