With Korea, the US basically conquered half of it and made it kind of territory or vassal. Vietnam would be the only victory for the belligerent. The Middle East with US intervention is pretty much destroyed, where Iraq is more or less a vassal state and Afghanistan is still out of control but more or less destroyed, and Syria is burning. In foreign cases the invading army will eventually leave the country if you can make victory for them too difficult politically or militarily, not so if the army is domestic.

I'm not a student of military history but these all seem disparate examples that don't support the point that you're trying to make. Are you trying to say something about the nature of the US Military's (in)ability to hold territory or making a point about foreign occupations?

Iraq is hardly a US vassal state any more. At this point Iran probably has as much or more influence.
