The analogy to 1914 is appropriate. But its lessons that Europe, the United States—and Russia!—should heed now are not limited to the pre-World War I war period, to the unpredictable and uncontrollable nature of political brinkmanship and military escalation, the danger of misreading adversary intentions and sending ill-conceived messages. The danger is also in not drawing lessons from the post-World War I period. Then, major powers failed in one crucial respect: they failed to devise a blueprint for Europe that would have enmeshed the vanquished nation—Germany—in a new European security framework. Europe paid a horrible price for that failure in World War II, but the West learned the lesson of the previous disaster and secured Germany in a web of trans-Atlantic institutions thus ensuring its role as the model European citizen.

However, what was done for Germany in the 1950s was not done for Russia in the 1990s after the West “won” the Cold War and the Soviet Union collapsed. Despite early misgivings about post-World War II Germany’s fate in a new European security order, the part of Germany occupied by the United States, France and Great Britain joined NATO in 1955 and was fully integrated in the West. Its place in Europe was never in question.

That was not the case with Russia after 1991. Its place in a post-Cold War Europe whole and free was tenuous even in the best of times. The possibility of NATO membership was never under serious consideration, and whenever this idea came up (be it from Yeltsin or Putin), it was always treated as a far-fetched, theoretical possibility. The necessity of devising a new security arrangement to replace both Cold War structures—the Warsaw Pact and NATO—was never considered. There never was any question about NATO’s future after the Cold War, it would continue, period.

Moreover, NATO would expand. NATO’s enlargement to the East, not explicitly intended to threaten Russia, nonetheless had a hedging element even if the primary purpose was to cement a post-Cold War role for the United States on the Continent. If Russia failed in its transformation and reverted to its old expansionist self, NATO enlargement would provide Central Europe with the security umbrella that would guard against Russian encroachment. In the words of some of the earliest and most active advocates of NATO enlargement, Russia was a “special case.” Its place in Europe was a matter of grave doubt:

“Russia nevertheless remains a special case due to its size, geostrategic position and long imperial tradition. Many Europeans believe that Russia is not a European country, is unlikely to become one and should not be allowed into core European institutions. Indeed, at the moment not a single Atlantic alliance member is in favor of allowing Russia into either the EC or NATO, although most avoid saying so openly.”

The possibility of the EU (then European Community) membership for Russia was not on the table either.

In other words, whereas Russia’s former satellites in Central Europe and the Baltics had a clear destination at the end of their post-Communist transition and a guaranteed place in Europe’s security and political structures, Russia did not.  It would have to prove its European identity.

The cautious approach was understandable. Russia’s size, history, political culture, military traditions, as well as its geographic position on two continents, made integrating it a daunting, perhaps impossible task. Crucially, it saw itself as an integrator, not an integree. The result was Europe’s and the United States’ two-pronged approach to Russia: one element of it was to hedge against Russian resurgence as an adversary; the other element of Western strategy was to engage Russia, and encourage its transformation in the hope that it would see the benefits of market, democracy and joining the West (albeit on the West’s terms).

But in the words attributed to former New York mayor Rudy Giuliani and used by many others, “hope is not a strategy.” The United States and Europe had a strategy for Central Europe. They never really had one for Russia. Russia remained outside the key European institutions, it was not enmeshed in the trans-Atlantic political and security network as Germany was after World War II, while Russia’s economic ties to Europe and the United States have been turned into a potential vulnerability for both sides as a result of the Ukraine crisis.

The entire European political and security architecture was built on the foundation of two institutions—the European Union and NATO—which did not include Russia.  To advance its fundamental vision of Europe whole, free and at peace with itself and its neighbors, Europe and the United States relied on the hope that Russia would eventually embrace them on its own accord. Well over two decades into the post-Cold War era, this approach to European security turned out to be a huge gamble. It paid off in Central Europe. But not in Russia.

The Ukraine crisis is undoubtedly a cataclysmic event for Europe. But Ukraine is not the cause of the crisis. It is rather a symptom of the even larger problem for Europe. Europe’s problem is with Russia, its rejection of the security architecture devised and promoted by the West since the end of the Cold War.

Europe’s and the United States’ principal political, security, and economic challenge for the coming years is to develop a new strategy for dealing with its giant neighbor. This strategy will have to be built on a realistic understanding of Russia as it is, rather than on what the West would like it to be and hopes it will one day become. This challenge will not, cannot be addressed at the upcoming NATO summit in Wales. But the best that NATO leaders can do when they convene in Wales in a few days is to recognize the magnitude of the real problem facing the alliance and task their governments to begin the difficult work of developing such a strategy. Unless they do so, the summit will be remembered only as a missed opportunity.
