Today's flare-up between France and Italy was a preview of the European parliamentary elections, coming up in May.

Célia Belin, a former French diplomat now at Brookings, says, "For the first time, [those elections] will be fought on European issues, not on national issues," and Macron and the Italian populists "represent two pure versions of what's going to be offered."
- Belin argues that Europe is "now entering a phase where the political fight is in Brussels. It is now a place where you have parties and platforms, and the direction might shift very much if a new party wins."
- That's driven in part by geopolitical factors — an assertive Russia, trade wars, immigration — that demand European, not national, answers.
Between the lines: Belin says that on issues like those, nationalists around the continent "have common values but not common policies." As recent twists in France-German relations show, though, the same could be said of the multilateralists.
- The nationalists have stopped talking about leaving the EU, and are focusing on changing it. “I think Brexit probably was the best vaccination against any future exits," Rinkēvičs told me.
