A year ago this week, Donald Trump, with an aggressive rhetorical flourish, announced a range of tariffs against trading partners across the world. His “liberation day” levies attracted deserved derision. They were based on an unfounded state-of-emergency legal premise, and a dubious mathematical formula that ended up imposing tariffs on, among others, an archipelago of sub-Antarctic islands inhabited only by penguins.
The liberation day tariffs have failed so far on all fronts: practical, economic, political and legal. Trump was forced to reverse them a week later after a toxic reaction in financial markets, returning four months afterwards to impose a less drastic set of duties. They have shown no signs yet of achieving their various contradictory aims, including closing the overall trade deficit and bringing manufacturing jobs back to the US.
They are also deeply unpopular with the US public — Pew Research found six in 10 disapproved of Trump’s increased tariffs — and business. To top it all, the Supreme Court declared them unconstitutional last month, forcing Trump to rush to replace them with only slightly less arbitrary tariffs based on the balance of payments, unfair trade and national security.
