During a testy joint press conference at the NATO summit in London yesterday, President Donald Trump and his French counterpart, Emmanuel Macron, argued openly over how the 70-year-old alliance should handle Russia, the Islamic State, and Turkey. When interacting with allied leaders, Trump’s predecessors have generally followed a golden rule: Disagreements with friends are okay—but only behind the scenes, not in public.

Trump, in contrast, seems to relish going after the Europeans in full view of the rest of the world.

The United States has always been the most powerful NATO member, and every American president until Trump has been the alliance’s natural leader.
