Forget quiet, back-channel diplomatic communications. President Trump grabbed a bullhorn, walked into the center of a mass of people, and blasted five words that reverberated off the walls:

"Take it or leave it!"
Twelve countries will receive letters from the president tomorrow, notifying them that their 90-day grace period is about to expire, much like a person realizing too late that their coffee was not decaf.
If they miss their July 9 cutoff, tariffs of up to 70 percent will hit them like a falling piano on a sidewalk.
The FO'd, and now they will FA.
