America's post-9/11 role

It has been 12 years since thousands lost their lives in the gravest act of terrorism to occur on American soil. There is no doubt that the attacks on September 11, 2001 have had a lasting impact on American foreign policy, especially with the consequent launch of the global "War on Terror".

From the wars in Iraq and Afghanistan, to the operation that killed Osama Bin Laden, the U.S has not given up on its commitment to fight terrorism globally. But as the tensions in Syria heightened this past month, a new debate has emerged about the scale and nature of America's role in the world.

In this debate, Becky talks to former U.S Deputy Defense Secretary Paul Wolfowitz and prominent American political scientist Joseph Nye about American foreign policy since 9/11, and what the future may bring.
