MOSCOW — Germany's ex-Chancellor Gerhard Schroeder is a legend in Russia. He serves Gazprom's interests for a measly couple of million euros a year, sits in on sessions of the Russian Academy of Sciences, and writes books about his staunch friendship with "Genosse Wladimir," who, in the not-so-distant past, earned himself the well-deserved nickname of "Stasi" among business circles in gangster-ridden St. Petersburg.

But it is not immediately obvious whether it is Schroeder licking Vladimir Putin's boots nowadays or vice versa. The two are building, or trying to build, the Nord Stream gas pipeline, an exceptionally costly project that satisfies twin strategic objectives. Demonstratively hostile to the interests of both Belarus and Ukraine, the pipeline is intended to ensure that these countries are under Russia's energy thumb, regardless of who is in power.

As a bonus, the pipeline will also consolidate the Russian economy's status as an appendage of Germany's — its supplier of natural resources. Some of Schroeder's predecessors as German chancellor sought to attain the same objective by rather different means.
