Here are seven major questions left unanswered on Trump’s proposal: Trump only said he was “authorizing” the U.S. Trade Representative and the Commerce Department to impose a 100% tariff on foreign films. He didn’t say he would do it. With previous tariff threats, Trump has sometimes made good and sometimes backed off in the face of pressure.

In a post Sunday night on his Truth Social platform, Trump said he has authorized the Department of Commerce and the Office of the U.S. Trade Representative to slap a 100% tariff “on any and all Movies coming into our Country that are produced in Foreign Lands.”

Declaring foreign film production a national security threat, the president said he had asked his top trade official to start the process of imposing a tax on Hollywood.
