As a presidential candidate, Donald Trump gleefully painted his opponents as trigger-happy interventionists who would get the United States bogged down in all manner of foreign wars — up to and including World War III.

As president, Trump has racked up an astonishing list of countries he’s both threatened to attack and actually attacked.

Trump added a new entry to that list on Wednesday, threatening to strike Oman if it tries to control the Strait of Hormuz along with Iran.

“Oman will behave just like everybody else, or we’ll have to blow ‘em up,” Trump said at a White House Cabinet meeting.

It was particularly striking because it was phrased like an aside — something Trump seemingly casually dropped with little thought beforehand.
