In a world still reckoning with the boundaries of economic sovereignty, the United States has once again turned to tariffs as both shield and statement. President Trump, having seen his earlier trade measures struck down by the Supreme Court, has now anchored new duties of 10 to 12.5 percent on 60 nations to a more legally durable statute — one rooted not in emergency powers, but in the long-standing language of unfair trade and forced labor. The move covers nearly all of what America imports, and signals that protectionism is not a passing posture but a governing philosophy.
