But once they take a nap and rest a little bit, they won’t be so tired anymore.

Sometimes Germany was too weak, sometimes too strong. Or, as Henry Kissinger, a former American secretary of state, put it, referring to Germany just after unification in 1871, it was “too big for Europe, but too small for the world”. Today, Mr Simms (Cambridge University) argues, “it sits uneasily at the heart of an EU that was conceived largely to constrain German power but which has served instead to increase it, and whose design flaws have unintentionally deprived many other Europeans of sovereignty.”

The question is whether Germany can use its power by unapologetically leading. Given Germany’s past, its political culture militates against even trying.

“It’s nice to go to a conference of ‘young leaders’, but you don’t want a conference of ‘junge Führer’.”
