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

All the world's nuclear-armed states (except for North Korea) have begun modernizing and upgrading their arsenals, leading many observers to predict that the world is entering a new nuclear arms race. While that outcome is not yet inevitable, it is likely, and if it happens, the new nuclear arms race will be different and more dangerous than the one we remember. More nuclear-armed countries in total, and three competing great powers rather than two, will make the competition more complex. Meanwhile, new non-nuclear weapon technologies — such as ballistic missile defense, anti-satellite weapons, and precision-strike missile technology — will make nuclear deterrence relationships that were once somewhat stable less so.

Claims that drones will soon remake warfare or international politics are unwarranted. Although almost a dozen states now possess armed drones, and more are racing to acquire them, they will not play a decisive role in interstate conflicts. Drones will rarely be “winning weapons,” because they are vulnerable to air defenses. States will, however, continue to use drones against terrorists and domestic opponents.

"For nearly a century, in short, offshore balancing prevented the emergence of dangerous regional hegemons and pre­served a global balance of power that enhanced American security. Tellingly, when U.S. policymakers deviated from that strategy—as they did in Vietnam, where the United States had no vital interests—the result was a costly failure."

"In Bargaining on Nuclear Tests the historian Or Rabinowitz demonstrates the rare ability to engage with contemporary policy debates on nuclear proliferation and U.S. nonproliferation strategies on the one hand, and successfully utilize qualitative analytical frameworks in social science like prospect theory (19) on the other."

Many accounts suggest that the United States did little to prevent Israel, Pakistan, and South Africa from developing nuclear weapons. These accounts are flawed, however. The United States did attempt to stop all three countries from acquiring the bomb and, when those efforts failed, to halt additional proliferation measures such as further testing and weaponization.

When do states acquire nuclear weapons? History shows that only two types of states decide that the bomb is essential to their security: 1) very powerful states; and 2) weak states that lack ironclad security guarantees.

Al-Qaida has established a metanarrative that enables it to recruit militants and supporters. The United States and its allies can challenge its ability to do so by delegitimizing the ideological motivations that inform that metanarrative.

Many academics and policymakers argue that the removal of leaders is an effective strategy in combating terrorism. Leadership decapitation is not always successful, however. A theory of organizational resilience explains why some terrorist organizations survive decapitation. Application of this theoretical model to the case of al-Qaida reveals that the deaths of Osama bin Laden and other high level al-Qaida operatives are unlikely to cause significant organizational decline.
