Top Former CIA, Treasury Official David Cohen on What Makes Sanctions Bite

In this episode of Intelligence Matters, host Michael Morell speaks with David Cohen, former Deputy Director of the CIA and Under Secretary for Terrorism and Financial Intelligence about whether, when, and how targeted financial sanctions work. Cohen explains why the U.S. sanctions snapping back on Iran's oil industry may not have the same bite they did years ago, and why the Trump's administration's once-effective North Korea sanctions may have been weakened by the Singapore summit. Cohen describes how secondary sanctions expand the reach and enhance the power of U.S. financial sanctions, and how intelligence helps determine whether a given sanctions regime is effective.
