When incompetence in the Kremlin turns murderous, its incumbents can begin to tremble. As news of the downing of Malaysia Airlines Flight 17 over Ukraine trickled into Russia, people with a long memory recalled the Soviet Union's attack, 31 years ago this September, on Korean Air Lines Flight 007, and its political consequences.

Back then, the Kremlin first lied to the world by saying that it had nothing to do with the missing KAL plane. Later it claimed that the South Korean jet was on an American spy mission.

Within the Soviet leadership, the incident was a tipping point. It ended the career of Marshal Nikolai Ogarkov, chief of the General Staff and a hardliner of the hardest sort, whose inconsistent and unconvincing efforts to justify the downing of the plane proved deeply embarrassing to the Kremlin.
