I guess Germany and Japan would be too far back for you... How about the former Yugoslavia? I've been to Croatia and it's lovely. They needed some help and some international meddling, but it's a great vacation spot today. Dubrovnik is pretty much rebuilt. Even Serbia is a lot better than it used to be. It's not a utopia but muslims aren't being dragged off and murdered en masse either. It took a lot of NATO troops to accomplish that, working with the people of those countries.
Now, do you want to discuss some examples of where our not meddling has turned out really well in the last few decades? Rwanda? The Sudan? In the end, none of that matters. Afghanistan is Afghanistan. It's unique.
What makes you think the west has not meddled in Sudan ,Rwanda, Congo, Somalia, Hati? Find me a place that the west has not meddled. Western intervention has crippled developement in all those places and many more. How do you think we support our high standard of living?
