CQ Roll Call foreign policy reporter Rachel Oswald discusses her summer 2015 Pulitzer Center-supported reporting trip to Moscow where she focused on how the breakdown in U.S.-Russia strategic relations was impacting nuclear security, arms control, and nonproliferation. In her interviews with retired Russian military officers, former Duma members, and scientists, she was repeatedly told that the potential for a nuclear misunderstanding during a moment of crisis had not been this high since the 1962 Cuban Missile Crisis. The breakdown in relations has negatively affected the two countries' ability to cooperate in securing vulnerable Soviet-era nuclear materials and has harmed prospects for current and future arms control treaties.
