I'm not defending the US, but that's a dangerous slippery slope you're on that ends with no one being responsible for anything because free will is an illusion.
Your attempt to short circuit any rebuttals with infinite regress aside, this didn't happen organically or spontaneously - humans caused this, and I can give you the names of many of them.
I asked a simple question and I’m already on a slippery slope? That way any counter-argument is a slippery slope.
The logic of my question lies in the fact that the US played the biggest role in recent Middle East history. Why would a country with the biggest economy/military complex in the world bother to involve itself? This is an open question I don’t have an answer for. I’m sure that anyone in power does not do anything in altruistic nature though. That certainly includes Feds/governments.
You’re right on point though, free will is an illusion.
