The victors and the vanquished of the unipolar world order will assemble around the loaded caviar-and-vodka high tables of the Silver Whisper later this week. They will genuflect before the overlordship of Tsar George Bush as they sail gently down the Neva river in St Petersburg, even as Knyaz or Prince Putin picks up the tab for a party the Romanovs would certainly have approved of. And what a party it’s going to be. Forty-three heads of state and government, including Prime Minister Atal Behari Vajpayee — all carefully selected for their new and old world status by a Kremlin acutely conscious of the weight of its history. Not only the fact that it was once, hardly a decade ago, a superpower, but also that Peter the Great — in whose memory the 300th anniversary of St Petersburg is being celebrated — was a truly modern Tsar who decided that medieval Russia must open a ‘‘window to Europe’’.
