U.S. President Donald Trump used his Truth Social account on 31 July 2025 to mount a forceful defence of his tariff agenda, declaring that the duties are “making America great and rich again.” Trump asserted that tariffs, previously wielded by foreign nations against the United States, are now helping reverse what he called decades of economic harm inflicted by “dumb, pathetic, and crooked politicians.” The president also offered public encouragement to his legal team ahead of what he described as “America’s big case today,” warning that without the ability “to protect itself by using tariffs against tariffs, we would be ‘dead,’ with no chance of survival or success.” Trump did not detail the specific case, but framed the broader tariff authority as essential to national economic security.
