Calder Walton writes that China's clandestine services are on the front line of Beijing's grand strategy: to keep the Chinese Communist Party in power and to make China the world's leading and self-sufficient military and economic power. The aim is to invert the technological landscape so other countries depend on Chinese, not western, technology.

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 says both seek to topple the United States from atop world stage, with China's blend of money, influence, all-hands-on-deck approach posing the greater threat.

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

Dan Snow is joined by Calder Walton to talk about whether there was a huge intelligence failure around the outbreak of the pandemic, but also whether our intelligence communities are properly organized to realistically evaluate the real nature of the threats to our societies. He also has a bold idea to help avoid a future recurrence.

Calder Walton describes four ways how intelligence services are certain to contribute to defeating COVID-19 and why pandemic intelligence will become a central part of future U.S. national security.
