Sure the US has instigated plenty of crap but your comment is hyperbolic to the point of insanity and belittles damn near every regional power on the globe.
People are perfectly capable of starting wars with each other without the help of the US and if these people truly need help getting to the point of shooting each other the US is not the only nation with an intelligence agency capable of helping them out.
The only way that was first debunked by the war in Iraq would be if people picked up a world history book that started with the war in Iraq. I cannot think of an exception where the US didn't chose their interest over a democratically elected governance.
so the conflicts the US instigated were inevitable, and the US might as well have gotten involved for its own benefit? I hope this is not what you're saying but it sure sounds like it is.
