The dangers are real.

We have entered a new age where the risk of nuclear use—deliberately or by accident or miscalculation—is growing.

Regional tensions, the proliferation of nuclear weapons and materials to make them—along with terrorism and new technologies like cyber—mean the risk of a nuclear weapon or device being used is rising. At the same time, governments’ ability to manage increasingly complex global security risks is eroding.
