We should never been in the Balkans. Bosnia or Kosovo.
We chose the wrong side.
To me, it's not about picking sides. It's not our beef. We did not learn from WWI. With the assassination of Archduke Franz Ferdinand.
I think history will agree on your first point. It was a ridiculous boondoggle at best, and a dangerous foreign policy mistake at worst (that we’re still paying for).
We didn’t pick the wrong side: There were NO good sides, just degrees of criminality and evil, backed by some of the best propaganda machines in history. (America) fell for the CNN/Bono/Saudi Arabia information ops campaign. Again.
We should never have been there to begin with, but reminisce with me for a moment about the “humanitarian” 90’s: Desert Storm, Somalia, Haiti, the Balkans...we were played each time.
Somebody(s) got real rich though...
Cheers
