Only on the "CBS This Morning" podcast, former U.S. Ambassador to the U.A.E. Barbara A. Leaf and Middle East expert Vali Nasr talk with CBS News senior foreign affairs correspondent and moderator of "Face the Nation" Margaret Brennan about the impact the killing of Iranian general Qassem Soleimani is having on the region. Ambassador Leaf discusses the role Soleimani played in Iraq and Syria and why Iraqis have taken to the streets recently to protest. Nasr shares how Soleimani has provided Iran with a sense of nationalism but economic problems still exist in the country.
