Over the last several weeks, North Korea has launched an unprecedented number of missile tests. In one week alone in early November, North Korea launched over 80 missiles, including short and long range ballistic missles.

So why is North Korea suddenly flexing like this? And what do these missile tests suggest about North Korea's nuclear strategies and intentions? I put these questions and more to Kelsey Davenport, Director of Nonproliferation Policy at the Arms Control Association. We kick off discussing the kinds of technologies that North Korea is testing and then have a long conversation that puts these tests in context of geopolitics, US policy towards North Korea and more.
