Engaging in breathtaking displays of selective memory, Boris Berezovsky and the Putin administration he helped bring to power spent much of last week exchanging allegations of horrible crimes. Berezovsky, the exiled billionaire who was one of the most influential figures in Boris Yeltsin's Kremlin, accused Vladimir Putin of complicity in devastating bombings of Russian apartment blocks in 1999 that killed over 200 people in Moscow and the small southern town of Volgodonsk. The Russian government refused to respond to the allegations, but announced that Berezovsky was being investigated for links to Chechen guerrillas.
