Impressive as all this was, it’s not even the most important or unprecedented achievement of the EU. For half a century or so, Western Europe was at peace with itself and the world. Democracy became entrenched in countries that were primarily associated with fascism, and a genuine sense of “Europeanness” took hold. Young people in particular simply could not imagine crossing unguarded national borders to kill their counterparts in parts of Europe where they had often worked or been educated.
Europe was also the principal beneficiary of the “peace dividend”, especially following the unexpected and bloodless end to the Cold War. Little wonder some celebrated the “end of history”. As we now know, history didn’t end, and the Europeans are consequently castigated as naïve freeloaders unprepared for the seemingly inevitable power struggles and contests that characterise international politics.
If the so-called realists are right, the future doesn’t look good. At best, we may have to live in a world controlled by nineteenth-century-style “spheres of influence”, in which powerful authoritarian states – including our notional protector, the United States – dominate their regions. At worst, an intensifying arms race may end as they usually do: in unwanted conflict. Only this time, it could lead to a nuclear conflagration.
International cooperation is plainly not easy, but the EU, for all its problems, managed to achieve this, albeit by creating powerful institutions that directly impinged on national sovereignty. It is the only example we have of enduring, effective transnational cooperation between sovereign states. Its lessons ought to be studied, not vilified, especially as Europe also provides the most powerful example of all that can go wrong without a commitment to institutionalised forms of collective effort.
Ironically, the United States may be about to demonstrate the dangers of tearing down such institutions, and the rules and norms they embody, as it lurches towards authoritarian rule. Unfortunately, this means Americans are unlikely to provide enlightened leadership for themselves, let alone the rest of the world at this especially fraught historical juncture.
That’s the other thing the European experience demonstrates: leadership matters. In a further irony, it’s important to remember that, as Europe’s post-war reconstruction demonstrates, “American hegemony” really can be a positive and productive force, which is something else we might hope Trump and Vance would remember when they give comfort to autocrats everywhere. Democracy, peace and cooperation don’t happen by accident. Unfortunately, the EU is now looking like a miraculous aberration.
