The Sochi Winter Olympics, which begin next week, will forever be known as Putin's Games. However they eventually pan out, Russia's President has staked a good deal of political capital on their success -- not to mention plenty of actual capital, too -- and his legacy will ultimately be coloured by that of the project he has spearheaded from the get-go. At more than $50 billion, Putin's Games can claim to be the most expensive in history, costing five times more than original estimates, $10 billion more than Beijing, and more than all previous Winter Olympics combined. They have already won gold by a significant margin in terms of alleged corruption as well. Whether or not they become the most violent -- and terrorist attacks in Volgograd in December have raised concerns that they might -- remains an open question.
