Reformation, Revenge, Revolution: 2011 in Review

It was a turbulent and tumultuous year and as it comes to a close, Christiane Amanpour looks back on the stories that defined 2011.

Whether in a helicopter flying high above Japan in the wake of the earthquake and tsunami, interviewing President Hosni Mubarak in Egypt or Colonel Gaddafi in Libya, Christiane Amanpour was a firsthand witness to the news breaking around the world.

From the instability of the European financial markets to the worldwide protests that began in the Middle East and to Wall Street and Moscow, much of the tension from 2011 will reverberate into the New Year.

With mixed emotions the United States mourned the 10 year anniversary of 9/11 and celebrated the elimination of Osama Bin Laden. And as the American war in Iraq came to an unceremonious end, soldiers continue to fight in Afghanistan.

On our year end special, Christiane Amanpour takes you Around the World one last time before 2012.
