Former U.S. Ambassador to the United Nations John Bolton says the U.S. call for Syrian President Assad to step down is correct but comes far too late. Why does he say it’s the right move?

Bolton addresses those questions, examines the role of an eroding relationship between Israel and Egypt in this week’s terrorist attacks and updates his consideration of joining the 2012 presidential campaign. Listen here for the full interview with John Bolton.
