You're probably right on all counts, since many people simply wouldn't want to be liberated in the first place.
If we had totally won in Korea and not come to a stalemate instead,...I doubt very much if The North Koreans would've appreciated being liberated.
If we had totally won in Vietnam instead of politically forced to bail-out,...I doubt very much if The North Vietnamese would've appreciated being liberated.
Even though totally winning in what was once Jugoslavia, not many there appreciate being liberated,...much like as in Iraq.
In fact, it's a pretty-much given that as soon as any foreign policing and stabilizing forces leave, all factions that have hated each other for generations, if not for hundreds of years, will once again keep killing each other for sport, power and control,...just as done before. It's practically inate.
Sure, I hope I'm wrong. But, unfortunately and historically I just can't see it any other way. Regardless, and since all terrorist types need killing wherever they can be tracked-down,...I do believe that doing so in Afghanistan and Iraq were/are the right things to do. The more the merrier,...and less of those bums that we will have to face here at home.

P.S. HC...Don't know what happened. Ended-up with 2 identical replies. Wasn't able to delete one, so you'll just have to be satisfied with this explanation.
