As the coronavirus pandemic sends the global economy into a swoon, Europe’s eye-for-an-eye strategy for managing a transatlantic dispute over aircraft subsidies could become collateral damage and hand the U.S. a negotiating advantage.

At issue is whether the European Union will have the political will to trigger planned tariffs against the U.S. over its illegal aid to Boeing. The 27-nation bloc is waiting for the World Trade Organization to set the ceiling on damages in a decision due in June.

In more normal circumstances, the political advantages of EU retaliatory duties would outweigh the economic costs. That’s because punitive import levies green-lighted by the WTO would let Europe use its well-honed ability to target American goods made in U.S. states that can swing elections and, in the process, defend global trade rules.

In the long-running transatlantic discord over government aid to plane manufacturers, another compelling political reason exists for the EU to pursue trade sanctions: The U.S. in October imposed duties on $7.5 billion of European goods in retaliation over unlawful subsidies to Airbus.

Not only did President Donald Trump’s administration ignore EU pleas to refrain from such action and focus instead on settling the matter at the negotiating table, it decided in February to raise the punitive tariff on Airbus aircraft to 15% from 10%. The increase took effect in mid-March.

In political terms, for the Europeans to negotiate an accord with the U.S. over aircraft subsidies while America has countermeasures in place and the EU doesn’t would be akin to one army in a war giving up its weapons before a cease-fire is agreed.

Enter the pandemic, which has inflicted massive damage on industries including aviation. As the U.S. and Europe unleash unprecedented economic stimulus, Boeing has sought a bailout and Airbus has urged authorities to support airlines and suppliers.

In that context, Europe might well reconsider the merits of imposing duties on billions of euros of American goods in the aircraft-subsidies feud simply because of the economic self-harm such a move would cause.

Trump himself has made any such European retreat even more politically tricky. The EU resents his 2018 decision to hit European steel and aluminum with tariffs based on national-security grounds and his lingering — if increasingly vague — threat to do the same against the bloc’s automotive goods.

One possibility: A European plan to forgo retaliation over unlawful subsidies to Boeing could be accompanied by a high-level plea from Brussels to Trump to scale back tariffs linked to Airbus. In the wake of Washington’s recent decision to let U.S. importers defer paying regular customs duties for three months as a result of the pandemic, a European request of that kind would look less fanciful.

On Tuesday, EU trade chief Phil Hogan expressed “hope” that both sides could reach a deal on aircraft subsidies before the WTO renders a verdict on damages in the Boeing case (while also saying “it’s slow, it’s technical” work).

More generally, Hogan said the EU and U.S. “should be working together in order to reduce tariffs, eliminate tariffs where possible” and to “reignite the global economy post the pandemic.”
