In the past, strategic surprise has often stemmed from a failure of imagination. Most intelligence failures are rooted in a lack of foresight or early warning of impending events. Blue sky thinking seeks to prevent these surprises by devoting more attention not just to known risks and likely scenarios, but also to low probability, high impact events. In an unprecedented step in forging ongoing global collaboration, 129 global experts gathered in Amman, Jordan, in December 2021. The conference was held under the auspices of Jordan’s Aqaba Process and facilitated by representatives from the Harvard Kennedy School Belfer Center’s Intelligence Project. Attendees included intelligence officers, diplomats, military officers, private sector practitioners, and academics representing 29 countries, 5 continents, and 68 government and private sector organizations. Through presentations and discussion under Chatham House Rules, the conference facilitated an open exchange of ideas on the possible next big threats from terrorism and on strategies for moving forward.

Contemplating the causes and effects of 9/11, as well as the experiences of those on the ground that day, yields useful insights into tackling today’s intelligence and policy challenges. This report is derived from 9/11: Intelligence and National Security Twenty Years Later, a full-day conference hosted by the Belfer Center’s Intelligence Project that examined the impact of the 9/11 through personal stories and policy reflections. It explores how strategic intelligence on Al Qaeda’s intentions failed to lead to policy changes that could have prevented the attacks on 9/11. It also examines how the U.S. can draw on the experience of 9/11 as it faces the specter of great power competition with China against the backdrop of globalized, existential threats posed by climate change and novel disease outbreaks like COVID-19. It also explores the critical nexus between intelligence warning and policy action. More broadly, the twentieth anniversary of 9/11 is an opportunity to reflect on who we are as a nation and who we want to be in confronting violent extremism—both at home and around the world.

The first half century of the nuclear age witnessed the gradual construction of a global nuclear order designed to mitigate nuclear dangers, inhibit arms racing, and prevent the spread of nuclear weapons to additional states. Spurred by the experiences, the dangers, the crises, the near misses, and the frightening risks on display in the early years of the Cold War, sustained efforts were made, in McGeorge Bundy’s vivid phrase, “to cap the volcano.” The time had arrived, Bundy wrote in 1969, for the two great nuclear superpowers “to limit their extravagant contest in strategic weapons,” a contest that had “led the two greatest powers of our generation into an arms race totally unprecedented in size and danger.” In the subsequent twenty-five years after Bundy’s appeal, an increasingly elaborate and institutionalized arms control process produced, with many ups and downs, a detailed web of constraints on the nuclear behavior of the superpowers. The articulated goal was to stabilize the superpower nuclear balance by reinforcing mutual deterrence. The vast nuclear arsenals of the superpowers, however, were not the only source of nuclear danger. In a world in which the number of states armed with nuclear weapons was slowly growing and many additional states had interest in acquiring such weapons or the technology to produce them, there was reason, as Albert Wohlstetter warned in 1961, to be “concerned with the enormous instabilities and dangers of a world with many nuclear powers.” Such a world—“life in a nuclear armed crowd”—Wohlstetter wrote in a later famous study, was widely believed to be “vastly more dangerous than today’s world.” The desire to prevent this unattractive world led to the negotiation of the Nuclear Nonproliferation Treaty (NPT), which entered into force in 1970, and to the subsequent development of an associated regime intended to create legal and technical barriers to the spread of nuclear weapons. Thus, in reaction to the major perceived dangers of the nuclear age, there emerged what Lawrence Freedman calls the “twin pillars” of the global nuclear order: mutual stability in the major nuclear rivalry and nonproliferation to inhibit or prevent the spread of nuclear weapons to additional states.

Fueled by aggressive rhetoric from both capitals, Indian and Chinese ground forces engaged in a standoff between June and August 2017. The Doklam crisis, as it became known, stimulated introspection among officials and experts in both states about the future of their relationship. Politically, both strategic communities largely concluded that the peaceful resolution of border disputes is now less likely, forecasting more rivalry than cooperation. Militarily, Indian discussions on the strength of its military position against China in their disputed ground frontier areas have converged on the view that China holds the conventional and nuclear edge over India in this domain.

Based on our analysis of data on the location and capabilities of Indian and Chinese strategic forces and related military units, we conclude that this assessment of the balance of forces may be mistaken and a poor guide for Indian security and procurement policies. We recommend that instead of investing in new nuclear weapons platforms that our analysis suggests are not likely to be required to deter China, New Delhi should improve the survivability of its existing forces and fill the gap in global arms control leadership with an initiative on restraint and transparency.
