President Trump threatened to attack Oman Wednesday if the Arab nation partners with Iran to assert joint control over the Strait of Hormuz. Iran has discussed partnering with Oman to charge tolls on ships passing through the strategic waterway, the New York Times reported last week. “It’s international waters, and Oman will behave just like everybody else, or we’ll have to blow them up. They understand that. They’ll be fine,” Trump said at a cabinet meeting.
