So tell me when the US should have not been involved? WWI? Let the Prussian empire roll over Europe? WWII? Let Hitler 'clean up Europe from less than desirable people. Or maybe later with Korea and/or Vietnam? Let these countries fall under control of Russia/China. Because yes, it is evident that these countries have a better societal model, just look at the millions folks immigrating there each year (unlike the US) . Your comment is an insult to all the folks who sacrificed their life to provide a better life to their compatriots.
