Former Undersecretary of Defense for Policy and co-founder of the Center for a New American Security Michèle Flournoy joins "CBS This Morning" to discuss why the U.S. is still in Afghanistan and why it's important for the U.S. to make a statement of commitment to supporting the country against terrorism.
