“We have to have an honest discussion with the U.S. if they are moving away from a rules-based trading system, and if and how we can rescue the existing system," said Lange, of the center-left Socialists & Democrats group.Tai — who represents the country that single-handedly tore down the WTO’s Appellate Body in 2019 under Trump and has refused to restore it ever since — said that the ruling “really challenges the integrity of the system.”She also blamed the decision on “unelected, not really accountable decision-makers in Geneva [who] second guess” America’s national security judgment.Post-WTO reality“A lot of people in Europe and Geneva have completely misunderstood ... that the United States have already moved on — they are already in a post-WTO reality,” said Hosuk Lee-Makiyama from the Brussels-based economic think tank ECIPE.He cites as proof Biden’s multibillion incentive package for Americans to buy green technology that’s made in the U.S., which experts agree violates WTO rules.“I don't see how the U.S. can be serious about maintaining the institution if it is not prepared to support the one mechanism that is designed to make sure that everybody plays by the rules,” said Lorand Bartels, an international law professor at the University of Cambridge."
