Even though Poland and its neighbors are members of both the EU and NATO, they don’t feel secure. Russia’s annexation of Crimea and its intervention in Eastern Ukraine have exposed these countries’ vulnerability. Furthermore, the Ukraine crisis has revealed a lack of unity inside the EU and NATO over how to deal with the security vacuum in this part of Europe and what strategy to adopt toward Russia.

As if that were not enough, the victory of left- and right-wing fringe parties in the recent European Parliament elections was a godsend to Moscow. Russian President Vladimir Putin could not have asked for anything better than to have anti-American, anti-NATO, anti-enlargement, and anti-globalization parties make big gains.

Obama has no illusions about Europe and its divisions, which he will hear firsthand when he meets other G7 leaders in Brussels on June 4–5. Once the United States had recognized the enormity of the Ukraine crisis, it began pushing its European allies to agree on sanctions against Russia.

The Europeans did put some measures in place. Yet Washington has had to go it alone in targeting prominent people that underpin the Kremlin’s economic power. To be fair, the United States stands to be hurt far less by sanctions against Russia than Europe does, a point that Obama has publicly acknowledged.

The Obama administration has also had little support from NATO countries to boost the defenses of Poland, the Baltic states, and, further south, Romania. Despite pleas from NATO’s top brass to show concrete solidarity, the big Western European countries have made clear that they will not deploy troops permanently or establish bases on NATO’s Eastern flank.

The German government, under pressure from a deeply pacifist public, believes such a move would provoke Russia. As if Russia’s own intervention in Ukraine was neither provocative nor militaristic!

Instead of NATO pulling together, it was initially the United States that unilaterally sent fighter jets to Poland and assisted the Baltic states, giving them much-needed physical and psychological reassurance vis-à-vis Russia. Obama may not want a military confrontation with Russia over Ukraine, but he certainly wasn’t going to abandon NATO’s Eastern members. His visit to Warsaw serves as a useful reminder to Putin—but also to the leaders of Britain, France, and Germany—that Washington stands with its allies.

The contrast to Western Europe’s attitude in this conflict is glaring. Both the EU and NATO will pay a high price over the way Poland and the Baltic states have had to lean on the United States.

Over the past few years, Donald Tusk’s center-right Polish government has invested much energy and support in trying to strengthen the EU’s foreign, security, and defense ambitions. Despite its deeply Atlanticist instincts, Poland shifted its strategy away from the United States toward Europe. Warsaw recognized that Europe, more than ever, needed a strong defense and security policy not only to compensate for America’s pivot toward the Asia-Pacific region but also to give Europe the ability to defend its values and interests.

As a result, Poland went out of its way to send troops to most of the EU’s missions abroad. It even campaigned for the EU to have its own military planning headquarters. Britain vetoed any such idea, fearing that it would undermine the transatlantic alliance.

All the more reason for Poland to feel disappointed now with EU’s feeble reaction to Russia’s incursion into Ukraine. That will carry a high price for the future of European integration.

Poland and its neighbors won’t be able to look to NATO, either, to strengthen their defenses. Instead, as the EU and NATO fumble over Russia, the northeastern part of Europe that consists of Poland and Estonia, Finland and Sweden, and Denmark, Norway, and Iceland could well end up forging a series of bilateral agreements with the United States.

Out of necessity, these northeastern European countries, which are for the most part Atlanticist, could create their own security clusters with support from the United States. Were that to happen, it would be an indictment of the unwillingness of NATO and the EU to pull together in times of crisis. Obama’s rhetoric in Warsaw will be no panacea.
