Saudi’s are an ally? At best they are an entangling alliance. Trump is sending our military to Saudi Arabia? He should be protecting the Kurds that stopped ISIS, not those that attacked us on 9-11. They are sent there as cannon fodder. We put ourselves in the ME which is always supremely foolish. Let those that live there deal with their own forever at war neighborhood.
The Kurds will protect themselves....they always have and do...on occasion we help....and likewise in return..
Saudi’s anther story altogether....arch enemy of Iran for power and control over there..and that includes the waterways for trade etc. So yes we will do what needs to be done to protect trade routes and the Iranian threat.
