Please. Where were these critics in August 2016, when then-Vice President Joe Biden attacked Donald Trump from foreign soil while on an official visit overseas? Speaking to allies gathered at a NATO summit in Riga, Latvia, Biden said Trump didn’t know what he was talking about when it came foreign policy. “Don’t listen to that other fellow. He knows not of what he speaks,” Biden said, pausing for emphasis before adding, “And he doesn’t know of what he speaks.” Biden continued, “The fact that you occasionally hear something from a presidential candidate … it’s nothing that should be taken seriously.”

Biden’s attack was not unprecedented, because just a few months earlier, President Barack Obama broke the norm by attacking Trump during an official visit to Japan. At a news conference in Ise City, Obama declared that Trump had “rattled” foreign leaders “because a lot of the proposals that he’s made display either ignorance of world affairs or a cavalier attitude or an interest in getting tweets and headlines instead of actually thinking through what it is that is required to keep America safe and secure and prosperous, and what’s required to keep the world on an even keel.” The Post reported at the time that “standing on the world stage Thursday, Obama showed no hesitation to attack Trump” and that the president had “obliterated the now-quaint political convention that partisanship stops at the water’s edge,” adding that “several historians said it was rare, if not unprecedented, for an outgoing president to criticize the foreign policy position of someone from the opposite party by name while traveling abroad.”
