Donald Trump left behind a series of national security problems that required changes in personnel, process, and policy. Biden’s initial appointments to high-level national security positions pointed to U.S. re-engagement with the international community that has been neglected for the past four years.

Finally, we will examine the possibility for reviving arms control and disarmament, which has been sorely neglected for four years.
