And if that message was lost on Beijing, Trump underscored it on Sunday, tweeting: "Did China ask us if it was OK to devalue their currency (making it hard for our companies to compete), heavily tax our products going into their country (the US doesn't tax them) or to build a massive military complex in the middle of the South China Sea? I don't think so!" He does not need Beijing's permission to speak to anyone. No more kowtowing in a Trump administration.

Trump promised during the campaign that he would take a tougher stand with China, and supporting Taiwan has always been part of his get-tough approach to Beijing. As far back as 2011, Trump tweeted: "Why is @BarackObama delaying the sale of F-16 aircraft to Taiwan? Wrong message to send to China. #TimeToGetTough." Indeed, the very idea that Trump could not speak to Taiwan's president because it would anger Beijing is precisely the kind of weak-kneed subservience that Trump promised to eliminate as president.

Trump's call with the Taiwanese president sent a message not only to Beijing, but also to the striped-pants foreign-policy establishment in Washington. It is telling how so many in that establishment immediately assumed Trump had committed an unintended gaffe. "Bottomless pig-ignorance" is how one liberal foreign-policy commentator described Trump's decision to speak with Tsai. Trump just shocked the world by winning the presidential election, yet they still underestimate him. The irony is that the hyperventilation in Washington has far outpaced the measured response from Beijing. When American foreign-policy elites are more upset than China, perhaps it's time for some introspection.

The hypocrisy is rank. When President Obama broke with decades of US policy and extended diplomatic recognition to a murderous dictatorship in Cuba, the foreign-policy establishment swooned. Democrats on Capitol Hill praised Obama for taking action that was "long overdue." Former President Jimmy Carter raved about how Obama had "shown such wisdom," while the New York Times gushed that Obama was acting "courageously" and "ushering in a transformational era for millions of Cubans who have suffered as a result of more than 50 years of hostility between the two nations."
