The brackets are now set. The competitors are laced up and ready to go. It's time to play World Leader March Madness, 2012.
Defending champion Barack Obama is back to defend his title this year, hoping that a second straight victory could power him through November. President-elect Vladimir Putin, fresh off a controversial election victory, is looking for revenge. North Korea's new supreme leader -- and reported basketball enthusiast -- Kim Jong Un, is looking to avenge his father's defeat in last year's competition. The Arab Spring revolutions have brought us both Tunisian Interim President Moncef Marzouki on the democrats' side and Egypt's military junta -- the SCAF -- facing off against regional powerhouse Mahmoud Ahmadinejad in the first autocrat matchup. And Bibi's back in the picture.
Notable first-round rivalries include Falklands/Malvinas pugilists David Cameron and Cristina Fernández de Kirchner, a demolition debt derby between Lucas Papademos and Angela Merkel, a battle of the reformist autocrats between Morocco's King Mohammed VI and Myanmar's Thein Sein, and an Middle Eastern Abdullah-Abdullah showdown.
