Biden Starts a Climate Trade War

Wasn’t President Biden going to end Donald Trump’s destructive trade wars against allies? Apparently not. His “super aggressive” climate protectionism—to quote French President Emmanuel Macron—is infuriating U.S. friends and may set off a subsidy and tariff war.

U.S. allies are upset about the Inflation Reduction Act’s generous subsidies for domestically manufactured green technologies. In his trip to Washington last week, Mr. Macron said the U.S. subsidies may “perhaps fix your issue but you will increase my problem.” They’re really a problem for everybody.
