There was a time, not so long ago, when Trump used tariffs to show the world he was the boss. Look at him sideways, or say something bad about him on social media, and he would shove a big tariff up your butt the next morning.
But the Supreme Court took that kind of arbitrary power away from him, and his military action apparently worked in Venezuela, so now he prefers bombs to tariffs. The next question is, how far will he go? Will the next victim be London? Mexico City? Ottawa? New York City?
