PRI's The World: 9/11/2014
13 years after the Al-Qaeda attacks of September 11th, America once again braces for war. But President Obama says it's a different target and a different kind of war. This time, the target is the Islamic State — or ISIS — and the war, the President says, will involve targeted air strikes and very few boots on the ground. Plus, we'll take you to Libya, where the talk is of the second anniversary of the attacks on the US mission in Benghazi. And, a new UN study shows that the ozone layer may be healing itself, at least in part because the world came together years ago and decided to stop using aerosol sprays.
