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

During the 1990 German reunification negotiations, did the United States promise the Soviet Union that it would not expand NATO into Eastern Europe? Although no written agreement exists, archival materials reveal that U.S. officials did indeed offer the Soviets informal non-expansion assurances, while keeping open the possibility of expansion and seeking to maximize U.S. power in post–Cold War Europe.

Despite their disagreements, proponents of deep engagement and offshore balancing share an optimistic but unrealistic assessment regarding the durability of U.S. military dominance. China’s antiaccess/area denial strategy and conventional precision-strike capabilities are already undermining the United States’ military dominance in East Asia. The United States will need to adapt its military to meet this challenge.

"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."

"Iran has always been a major power in that region. Under Saddam however, Iran and Iraq were bitter enemies who fought a long war and were strongly opposed to one another. There was almost a rough balance of power between the two countries. By reducing Iraq's power and by allowing the Shia to become the dominant political force in Iraq, the US removed the main country balancing Iran, and helped bring to power a government that has at least some sympathies and links to Iran. So, Iran is by far the main strategic beneficiary of the Iraq War, which made it even more difficult for the US and its allies to deal with the country."

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.
