15 Minutes is an interview podcast with the biggest names in the global security space. This week, The Cipher Brief’s National Security Reporter and Europe Analyst Kaitlin Lavinder speaks with Ambassador Alexander Vershbow, former Deputy Secretary General of NATO (2012-2016). A changing external threat environment, internal security concerns, and the rise of populist anti-EU political parties leave Europe in a vulnerable position in 2017. Alexander tells Kaitlin how NATO can play a vital role in European security, and how the United States serves an indispensable role.
