The US-EU trade war is mutually destructive. The two sides should finally negotiate.

When is a setback for U.S.-European trade not necessarily a setback for U.S.-European trade? When it’s Monday’s European Union announcement of $4 billion in new tariffs on U.S. goods, in retaliation for the Trump administration’s imposition of tariffs on $7.5 billion in European goods, ranging from aircraft to whiskey, last year. This latest round of tit-for-tat levies so clearly demonstrates the mutually destructive nature of transatlantic trade conflict that it may finally prompt both sides to negotiate a permanent settlement.
