The Cold War started earlier than we think — and maybe never ended at all. Historian Calder Walton says understanding the US-Soviet conflict prepares us for this era of tensions with Russia and China.

Calder Walton recounts how Russia and China are using their intelligence agencies to reverse the outcome of the Cold War

Calder Walton explains why, as the 20th anniversary of the U.S.-led invasion of Iraq passes, it is useful to understand how China's intelligence and national security establishment reacted at the time.

Hostile foreign states are using weaponized information to attack the United States. Russia and China are disseminating disinformation about domestic U.S. race relations and COVID-19 to undermine and discredit the U.S. government. These information warfare attacks, which threaten U.S. national security, may seem new, but they are not. Using an applied history methodology and a wealth of previously classified archival records, this article uses two case studies to reveal how and why a hostile foreign state, the Soviet Union, targeted America with similar disinformation in the past

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.

Calder Walton unravels the details of Operation NEPTUNE, a disinformation campaign by the former Czechoslovak intelligence service intended to smear public figures in West Germany through forged Nazi documents.

This essay makes three arguments. First, the US government will need to establish a coronavirus commission, similar to the 9/11 commission, to determine why, since April 2020, the United States has suffered more coronavirus fatalities than any other country in the world. Second, the COVID-19 pandemic represents a watershed for what will be a major national security theme this century: biological threats, both from naturally occurring pathogens and from synthesized biology. Third, intelligence about globalized challenges, such as pandemics, needs to be dramatically reconceptualized, stripping away outmoded levels of secrecy.

Calder Walton recounts the history of World War II which shows that Britain and the United States were in a Cold War with the Soviet Union before they knew it. The same is true today: Britain and the United States are in a Cold War with Russia whether policymakers in London and Washington like it or not.

Matt Chorley is joined by two experts on Russia — Dr Jonathan Eyal from RUSI and Dr Calder Walton from Harvard — to dissect the Russia report, published by the British Parliament's Intelligence and Security Committee, and look at the country's history of interference abroad.

Calder Walton writes that autocratic regimes — China, Russia and Iran — have been using social media to try to influence U.S. public opinion. History reveals how and why a one-party regime used disinformation to salvage its reputation following a disaster — the Soviet Union's 1986 Chernobyl nuclear catastrophe, whose history also reveals how such disinformation can be countered.
