Dear EU,
Force his hand. Call his bluff. He brand is smoke and mirrors. Make him enact a 200% tariff on all the French champagne his billionaire backers drink, but refuse to remove the targeted whiskey tariffs. His tell is his MAGA supporters are paying the price for celebrating his tariffs on you (even though perversely tariffs are paid by them), and they are pissed and he's afraid. This is how you NEUTER Trump. He's convinced them tariffs = strength, and they believe him. Don't let up. Make it worse. And by neutering him, you erode his US support and make his insanity a national family intervention problem and not a neighborhood trouble.
In 2017-2021, the US Democrats tried to apply norms, the Senate GOP put faith in norms, and refused to take the short term pain (by impeaching him making him ineligible for elected office and facing MAGA hate), they passed like dutiful chickensh*ts, so now we've ended up here.
I am sorry that Europeans will suffer because of retaliatory tariffs, but he is counting on you being weak, afraid, and caving. That's exactly how he, historically, operates. And if you cave now, the pain will be 100x worse. Look at America. This is you, if you cave. Don't go into slaughter politely, like our politicians did. It's only going to get worse. Sadly, Trump has declared the US your enemy.
