Trade embargos instead of tariffs

*The administration also called on its trading partners to abide by the IEEPA tariffs and expected that they would honor their previous deals. He noted that the Supreme Court had reaffirmed the President's right to a complete embargo, which could pose a "draconian alternative" for other nations.* What would happen if the president decided to launch trade embargos on the entire world instead of tariffs. Is anybody not alarmed that we are close to complete financial collapse and disaster.
