Of course the EU should retaliate against U.S. tariffs, even if there was a better prospect for a tariff deal. Deals are meaningless because Trump doesn't honor his own deals. Trump made a deal with Mexico a few months ago an earlier time that he threatened tariffs. And then, after a few months of Mexico abiding by the agreement, Trump announced even more tariffs against Mexico.
The only way to get Trump to back down is to retaliate hard against the U.S. in the hopes it will trigger a market meltdown, then Trump will back down.
