... SOMETIMES, just sometimes, you should pay attention to annoying things said by tiresome people at worthy conferences.

In 1994, I was half asleep at a round table in St. Petersburg, Russia, when a short, thickset man with a rather ratlike face — apparently a sidekick of the city’s mayor — suddenly piped up. Russia, he said, had voluntarily given up “huge territories” to the former republics of the Soviet Union, including areas “which historically have always belonged to Russia.” He was thinking “not only about Crimea and northern Kazakhstan, but also for example about the Kaliningrad area.” Russia could not simply abandon to their fate those “25 million Russians” who now lived abroad. The world had to respect the interests of the Russian state “and of the Russian people as a great nation.”

The name of this irritating little man was — you guessed it — Vladimir V. Putin, and I know exactly what he said back in 1994 because the organizers, the Körber Foundation of Hamburg, Germany, published a full transcript. For the phrase that I have translated as “the Russian people,” the German transcript uses the word “volk.” Mr. Putin seemed to have, and still has, an expansive, völkisch definition of “Russians” — or what he now refers to as the “russkiy mir” (literally “Russian world”). The transcript also records that I teased out the consequences of the then-obscure deputy mayor’s vision by saying, “If we defined British nationality to include all English-speaking people, we would have a state slightly larger than China.”...
