Americans might be forgiven for regarding Europeans as a puzzle. And not an intriguing one, but an irritating, what-the-hell-are-they-thinking kind of puzzle. The global survey books by American thinkers this year – Zbigniew Brzezinski’s Strategic Vision, Robert Kagan’s The World America Made and Ian Bremmer’s Every Nation for Itself – profess to be in frustration more than sorrow with Europe’s passivity. Why don’t they pay more to protect themselves and to project force? We do. Why can’t they unite into a federal state and get a properly integrated economic policy so they can get over this euro crisis? We did. Why can’t they get over their obsession with immigration – especially since their populations are shrinking, and they need more labor? We have.
