The disarmament euphoria of the first post-Cold War years has been replaced with enhanced attention to nuclear weapons. In the place of traditional missions assigned to nuclear weapons during the Cold War, new ones have emerged or became relatively more prominent--limited use in primarily conventional conflicts. The enhanced role of nuclear weapons is likely a result of the emergence of a new international system following the hiatus of the post-Cold War period. With the end of the Cold War, the primary mission of nuclear weapons, mutual strategic deterrence of two opposing poles of the international system, largely exhausted itself, leading to hopes that nuclear weapons would lose relevance. The disarmament momentum has, however, largely exhausted itself, at least in its traditional forms and priorities, as the emerging new international system is giving rise to threats and challenges that seem to require a "nuclear response". The emergence of a new, limited-use mission assigned to nuclear weapons increases the likelihood of actual use of nuclear weapons. The increase is modest--perhaps from effectively zero in the last years of the Cold War to maybe 2-3 percent in the future--but an increase nonetheless.

Lyman and Morrison will discuss the Council on Foreign Relations-sponsored Independent Task Force Report on the US and Africa. The Report argues that Africa is becoming steadily more central to the United States and to the rest of the world in ways that transcend humanitarian interests. Africa now plays an increasingly significant role in supplying energy, preventing the spread of terrorism, and halting the devastation of HIV/AIDS. Africa's growing importance is reflected in the intensifying competition with China and other countries for both access to African resources and influence in this region. A more comprehensive U.S. policy toward Africa is needed, the report states, and it lays out recommendations for policymakers to craft that policy. The report is available at www.cfr.org.
