Stephen Walt argues for a return to a realism-based U.S. grand strategy.

"Although the cancellation of the planned deployment of the SM-3 IIB interceptors has removed the possibility that interceptors deployed under the phased adaptive approach would pose a threat to Russian missiles, it has not diminished the missile defense system's primary mission of intercepting an array of current and potential future Iranian missiles. The restructured missile defense system would still theoretically be able to handle these Iranian missile threats, even if one factors in a comfortable amount of time for detecting and tracking them."

During the Cold War, the threat of a nuclear attack came mainly from the U.S.-Russian nuclear arsenals, writes Kevin Ryan. Today, however, the United States and Russia have been forced to adapt to a new nuclear threat—that of dedicated terrorists with money and technological access who seek to obtain and use a nuclear device.

The path of transformation that the leaders of the Soviet Union can choose depends critically on the extent of Western engagement and assistance is critically dependent on the path of reform the Soviet Union is prepared to undertake.
Therefore, rather than each side waiting for the other to take the first step, the governments of the Soviet Union and the West should jointly develop a common program of what each would do if the other meets specific conditions.

President Bush has called nuclear terror the defining threat the United States now faces. He's right, but he has yet to follow up his words with actions. This is especially frustrating since nuclear terror is preventable. Washington needs a strategy based on the "Three No's": no loose nukes, no nascent nukes, and no new nuclear states.

The debate over national security and arms control has focused primarily on weapons: more or fewer weapons, different kinds of weapons. During the 1984 presidential campaign, for example, President Ronald Reagan defended his administration's military buildup, the biggest in peacetime. Former Vice President Walter Mondale advocated a freeze on deploying new weapons. Numbers and types of arms have preoccupied governments and specialists on both the right and the left.
