Europe's Reluctance to Engage in Tit for Tat Trade Policy

Europe has been particularly upset at the subsidies involved in the Biden administration's inflation reduction act.

European bureaucrats, you're talking to people who spent their entire career from their university training onwards committed to the principles of multilateral trade liberalization and they don't flintrum them.
