Here’s an excellent article by the New York Times about Lukoil, Russia’s largest oil company (now that Yukos is on the verge of bankruptcy), and the oligarchs in general.
Very well written, and insightful in terms of detail. As a bonus, no strong liberal/political bias. Cynic in me says that’s because it’s written by a contributor rather than a staff reporter. In any case, content trumps provenance in my book, so enjoy.
