The question of whether European governments can deliver real defense capabilities (I remain skeptical) is overshadowed by the larger issue of what this says about where views on defense in Europe’s capitals seem to be. The recent proposal’s focus on creating EU defense institutions instead of shoring up transatlantic security is potentially bad news for both Europe and the United States, because rather than reconsolidating resources in NATO, it may in fact further divide Europe along national security optics. If the idea of greater EU defense capabilities is to move forward, it will inevitably draw on the strained capabilities of the NATO alliance, as defense spending and capabilities are a zero-sum game. Not surprisingly, perhaps, Russia’s President Vladimir Putin seems to be a fan of the idea given his determination to put more daylight between Europe and the United States when it comes to transatlantic security.

More importantly, European common defense, while presented as an attempt to mount a serious response to Europe’s deteriorating security situation, is maybe more than anything a reflection of the shifting power dynamic in the EU after the Brexit vote. The reemergence of the idea of EU defense suggests that there is a disconnect between the real requirements of fielding more capabilities to buttress Europe’s security, on the one hand, and the almost instinctive institutional response by the EU’s political class, on the other.

Discussing how to create more infrastructure in Europe or how to tweak the institutions doesn’t move the debate forward. This approach also raises the key question of how serious European governments are about making their defense effort mesh with that of the United States. That question is especially relevant today when America’s footprint in Europe has shrunk significantly and when the rapidly changing security landscape in Asia and the deepening crisis in the Middle East call on the United States to devote more resources to those theaters.

Perhaps even more significantly, talk in Europe of a new headquarters and new European defense structures is arguably the last thing the U.S. Congress and the American public need to hear (assuming the American people pay enough attention to what goes on in Europe). In a U.S. presidential election year in which the theme of “America first” has resonated with a large segment of the electorate, Congress may simply decide that the time has come to rethink the fundamentals of what the United States provides in terms of transatlantic security.

The proposal to reopen the debate on European defense also suffers from poor timing. Europe has effectively demilitarized over the past decade, and the notion of crafting another institutional adaptation in place of shoring up NATO speaks volumes about how disconnected internal EU debates on security have become from the realities on the ground. State-on-state conflict has returned to Europe’s periphery, borders are being redrawn by force, refugees and migrants are flowing into Europe at unprecedented levels, and the norm-based order is increasingly displaced by Russia’s geostrategic assertiveness along Europe’s periphery. In that context, the idea of creating a new European headquarters cannot but seem far removed from the real needs the transatlantic security community faces.

NATO has its share of flaws and needs to be reformed to meet the security threats of today and tomorrow, from a renewed emphasis on traditional territorial defense through counterterrorism to cybersecurity. But NATO is worth preserving and reinvigorating because it offers the most effective and time-tested link between the defense capabilities of the United States and Europe. EU leaders should stop wasting their time, energy, and, most importantly, money on another iteration of an EU security idea when the core transatlantic alliance needs bolstering. To insist otherwise is to run the risk that the U.S. public will take the Europeans at their word and begin distancing itself from the alliance.

In the end, calling for the creation of a new military headquarters and for the EU to get serious about forging military ties ensures that Europeans will again sidestep the issues of spending more on defense, improving coordination, and strengthening NATO. The new European defense initiative sends the disturbingly familiar message that the EU’s leaders are poised for another round of talking institutional change in place of addressing hard-power dilemmas.
