Trump claims the absolute right to end all business with countries like Switzerland, says there are 60 of them "living off the United States," demands to know why they pay lower interest rates. Either a threat to weaponize US economic coercion or confused ranting about interest rates. Possibly both. The US doesn't set global rates and Switzerland's economy doesn't hinge on American business. But that's not the point: he's signaling willingness to use economic punishment as a governing tool.
