President-elect Donald Trump won’t be sworn into office for another seven weeks, but he is already possibly destabilizing international relations and domestic markets by constantly threatening to impose new tariffs. In just the past month alone, he has threatened to impose a 10% tariff on all imports from China, a 25% tariff on all imports from Canada and Mexico, and a 100% tariff on all nine of the BRICS nations: Brazil, Russia, India, China, South Africa, Egypt, Ethiopia, Iran, and the United Arab Emirates.

Whatever other executive actions Trump may take or threaten to take, his power to impose new tariffs unilaterally is, unfortunately, quite expansive. If Democrats and Republicans don’t like this state of affairs, however, they have only themselves to blame. And time is running out for them to do something about it.
