Honestly the world would not care about the wars in the Middle East if the Middle East didn't have oil. I mean, Muslims are getting slaughtered in Myanmar and CAR, and that never gets coverage. Just think about the Second Congo War, the deadliest conflict since WW2, which killed approximately 10 million people between 1998 and 2003. How much coverage did that get? Almost none. What about the insurgency in Uganda? That has killed 65,000 people. Compare that to the insurgency in Yemen which gets a whole lot more coverage and has killed a measly 6,000 people. (Don't get me wrong, that's still 6,000 people too many)
TL;DR If a country doesn't have oil, the US doesn't care.
