The sanctions issue reaches to the core of Germany's relations with the United States and Russia, and inevitably leads to questions about Germany's international position and its global role. A quarter-century after the end of the Cold War, most Germans do not feel they really need U.S. military protection. Sixty-five years of stable democratic development and effective treatment of historical legacy issues allows the Germans to feel morally on a par with anyone in the West, including the United States. As the leading economy in the EU, Germany bears nearly the same amount of responsibility for the global economy as its Trans-Atlantic partner. This explains the outrage of so many Germans, including the chancellor, over the NSA electronic spying revealed by Edward Snowden. 

Relations with Russia have also undergone a major change. The gratitude to Moscow for letting go of the GDR, and pulling back its massive military forces from East Germany in exchange for a fairly modest compensation is gone with Helmut Kohl. Germany's advocacy of Russia in the councils of the West is gone with Gerhard Schroeder. Angela Merkel's own hopes for a modernized Russia are gone with Dmitry Medvedev's failure to win Vladimir Putin's approval for a second term in the Kremlin. The German media's campaign against "Putin's Russia" has finished off whatever remained of the special German-Russian relationship founded by Gorbachev and Kohl. Except, of course, for the 6,200 German companies doing business in Russia. 

Clearly, the "Post-Cold War era" is over for Germany. It is less clear what comes next. Germany may continue with its trademark economic activism and political abdication, which both makes it ever richer and helps avoid clashes with allies. Such a course, however, is increasingly less sustainable in the face of the challenges which Europe is now facing, and not only in the aftermath of the euro crisis. If anything, the Ukraine crisis is Exhibit A in the gallery of disasters rooted in the lack of strategic thinking and leadership in Europe. 

Germany may revise its passive abdication in favor of more Cold War activism vis-à-vis Russia. This, however, is rejected by the business community, the social democratic members of the ruling coalition in Berlin, a number of prominent political figures such as former chancellors Schmidt and Schroeder, and a group of "Russland-Versteher," ranking politicians and experts who claim to understand Russia and plead for an understanding with it. Despite the media efforts to the contrary, a surprising share of German public opinion support a moderate course toward Russia, and not only because of the economic gains they do not want to give up. 100 years after the start of World War I and nearly 70 years after the end of World War II, Angela Merkel may not agree with them, but she listens.

This brings us to the crux of the matter. Germany is slowly and carefully growing out of the constraints it had been living with since 1945. It is Europe's sole emerging power, and potentially a power in Eurasia. It knows it needs a continuing alliance with the United States, deepening integration with its EU partners, and a strategic approach toward Russia, China, India, and the rest of Asia. To rise up to the challenge, Berlin will need to develop two qualities rare in today's world: strategic independence and leadership—both on behalf of Germany itself and of Europe. 

Ukraine is a good place to start working toward that new role. For starters, Germany needs to stop thinking of Ukraine as a U.S.-Russian issue, and assume responsibility there on behalf of the EU as a whole, canvassing its partners' support for such an engagement. Merkel should let Barack Obama continue with his pivot to Asia, and free up John Kerry's time to deal with the Middle East, while engaging herself to help Ukrainians rebuild their country on an equitable and sustainable foundation. Ambassador Ischinger's appointment as the OSCE facilitator of the intra-Ukrainian dialogue is a useful step, as are Foreign Minister Frank-Walter Steinmeier's revived contacts with Sergei Lavrov. The chancellor, whose differences in worldview with the Russian president are well-known, needs to patiently pursue dialogue with Vladimir Putin on issues ranging from Ukraine and Moldova to energy and arms. Obama has no plans for a one-on-one with Putin in Normandy next month. Merkel has no excuse to miss the opportunity.

Germany's time to step up has come. With abdication no longer an option, the only question is whether it will lead or have to follow.
