Sunday night, Vladimir Putin had a Brezhnev moment. It was when he ceased simply being an elected leader and segued towards a lifetime presidency. Having neatly sidestepped the rules by doing a stint as prime minister (no Russian leader can serve more than two consecutive presidential terms) Putin can now go on and on. Brezhnev did 18 years, Stalin 31. Despite the whispers of revolution lapping at the Kremlin's walls, who would bet against Vladimir matching Leonid?
