If Saudi Arabia goes maybe a ton of Support for Terrorism will go with them
ISIS wants Mecca and Medina also. I think they are a different sect and are larger so they think they can win.
I don't see how that would be possible. Right now ISIS has neutral Turkey at it back.
But if ISIS went for those oil fields, it would have millions of hostile Shia (in southern Iraq) at its back. No way could ISIS overcome that.
This may be a stupid question but which countries buy the oil ISIS sells now? Or is that a big secret?
