“Perhaps President Trump will first explain why the U.S. has any reason to respond to an attack on Saudi Arabia.”
It’s been a de facto US policy since the end of WWII that we would ensure the free flow of oil in the world.
Ever heard of the Carter Doctrine? Even he was willing to risk existential war to do that.
Oil flowing out of the Persian Gulf is a core, strategic US interest. And has been for at least 75 years.
Effective attack on that flow will most certainly bring substantial war. Whether you or I or anyone else likes it or not.
If youre reduced to suggesting that President Trump should follow Jimmy Carters lead, then you may as well start planning Joe Bidens inauguration.
P.S. if oil flowing out of the Persian Gulf is a core U.S. interest, then why have we imposed an embargo on Iranian oil?
