International Security & Defense

Since its creation in 1947, the Central Intelligence Agency (CIA) has been at the heart of supporting United States foreign policy and national security decision-making. From the early days of the Cold War to Russia’s war against Ukraine, the CIA has been a critical instrument of foreign intelligence collection, analysis, and operations. However, the CIA is often misunderstood, as its own work and history, particularly its successes, are rarely seen by the public. To help unpack this storied history, and in honor of the agency’s 75th anniversary, on September 16, 2022, former directors, officers, scholars, students, and the public gathered to discuss the past, present, and future of the agency. 

After the mistaken U.S. bombing of the Chinese Embassy in Belgrade in 1999, China turned to information-age weapons to create a risk of escalation to nuclear war with the United States. This shift helps compensate for its conventional military inferiority.

On February 24, the international community took a catastrophic blow. Already battered by two years of the COVID-19 pandemic and deteriorating interstate relations, it stood in horror as Russian forces unleashed an unprovoked war on a neighboring country. Russia’s decision to invade Ukraine and reject Ukraine’s very existence as a separate state is ominous and highly momentous for the future of the world order.

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.

The costly Ground-based Midcourse Defense system remains unproven and unreliable in deterring North Korea’s threat to use intercontinental ballistic missiles. An airborne boost-phase intercept system may offer an alternative defense against North Korea without threatening Russian or Chinese deterrents.

Could a conventional war between China and the United States escalate to the nuclear level? An assessment of three mechanisms of China-U.S. inadvertent escalation—use-it-or-lose-it, unauthorized/accidental, and damage limitation—concludes that the risk of China-U.S. inadvertent nuclear escalation is extremely low.

Stephen Walt reflects on a group of influential intellectuals—and personal friends—who passed away in 2021.

What types of foreign policy cues are most likely to turn public opinion against a popular emerging norm? Since 2017, the U.S. government has sought to discredit the Treaty on the Prohibition of Nuclear Weapons and its nuclear nonpossession norm among the largely prodisarmament American public. The authors fielded a national U.S. survey experiment (N=1,219) to evaluate the effects of these elite cues as well as social group cues on public opinion. Their study thus offers one of the first experimental assessments of public attitudes toward nuclear disarmament.

The U.S. should accept with humility its inability to fully eliminate terrorism. Specifically, U.S. policy must balance “ends, ways, and means;” establish clear and achievable objectives; adopt efficient, effective, and resource-sustainable strategies; ensure synchronization of diplomatic and military efforts; build alliances to share the burden of countering terrorism; and leverage cooperative mechanisms and regional partnerships to increase the capacity and willingness of regional states to defend their sovereignty and contribute to multinational coalitions against terrorism.  A balanced, integrated, and synchronized strategy encompassing defense, diplomacy, economic, and humanitarian assistance lines of effort should be cornerstone of a revamped foreign policy in the coming decades.

The Biden-Putin summit in Geneva did not disappoint the very low expectations set out for it. To move beyond symbolism and signaling, however, the Biden-Putin proclamation has to be translated into practical progress.
