Trump needs to unload and unlock on this one and put his guns away. This is not our fight. The House of Saud has their own means to settle their affairs. Let them.
Debatable.
If Little Kim, under pressure from sanctions, started lobbing missiles into SK, would that not be a trip wire? Do we not have interests in the region and interests in not allowing piss ant dictators from firing off against the 'paper tiger'?
Do we not have billions invested in the Persian gulf region in the form of oil industry? Do we not have some obligation to those US interests and the US personnel who are over there?
Finally, do we not have a duty to keep shipping lanes free and open? (answer, yes we do)
Iran's actions over the last many months are direct threats and actions against all of these so 'this is not our fight' is a debatable subject.
The US people are tired of being the worlds police, and not interested in getting in more protracted wars, but we also aren't interested in sticking our heads in the ground while some raghead is kicking us in the ass. Sometimes your enemy doesn't give you much choice but to hit back.
