The founder of WikiLeaks, Julian Assange, says there may be evidence of war crimes in the 90,000, mostly classified U.S. military documents about the war in Afghanistan that the site posted over the weekend.  We take a closer look at Assange and how WikiLeaks got a hold of the documents with Clint Hendler, of the Columbia Journalism Review.

As newly-released documents re-ignite the debate on the Afghan war, we revisit our conversation with Greg Mortenson, co-author of "Three Cups of Tea."  In 1993, Mortenson was nursed back to health by Pakistani villagers after a failed attempt to climb K2.  He went on to build over a hundred schools mostly for girls in Afghanistan and Pakistan, including some in Taliban-controlled territory — leading the U.S. military to wonder how he does it.

E.U. foreign ministers today adopted their toughest-ever sanctions against Iran in response to the country's nuclear program. The BBC's Jonathan Marcus looks back at the wave of international sanctions on Iran so far and whether they have had any impact.

Since BP's oil disaster began in April, there's been no shortage of suggestions on how to prevent future oil catastrophes. Much of the focus has been on new regulations: The Obama administration is working to restructure the Minerals Management Service and there's been talk about giving the Coast Guard and The Environmental Proection Agency more oversight of offshore drilling. But our guest, Jody Freeman, says that in addition to "sticks" like regulation, there should also be more "carrots," that reward companies for taking safety precautions. Freeman is a professor at Harvard Law School, she was also counselor for Energy and Climate Change in the White House in 2009 and part of 2010.
