The Alarm on China's Nuclear Surge and AI War Risks
In recent public appearances, including key testimony before the Senate Foreign Relations Committee, Marshall Billingslea has issued stark warnings regarding the rapidly evolving global strategic landscape.
He has highlighted that China is aggressively pursuing a massive nuclear buildup, which, combined with advancements in Artificial Intelligence (AI), poses significant risks to global stability. Billingslea stated that China is now "on track to" achieve a nuclear capability that challenges the existing strategic balance. This testimony underscores a central theme of his current work: the urgent need for the U.S. and its allies to counter these emerging threats effectively.
His analysis extends beyond sheer numbers, focusing on the qualitative threat posed by new technologies. The integration of AI into military and strategic planning, particularly by China, is a major concern he has emphasized.
Furthermore, Billingslea has been a vocal critic of what he views as missteps in U.S. arms control policy, specifically criticizing the "arbitrary political extension" of the New START Treaty. He argues that the current U.S. nuclear modernization program is necessary but must be robustly supported to maintain credible deterrence in the face of China's and Russia's evolving arsenals.
Architect of Illicit Finance Policy and Global Financial Integrity
One of the most impactful phases of Billingslea's career was his tenure as Assistant Secretary for Terrorist Financing at the U.S. Department of the Treasury. In this role, he was instrumental in shaping and executing policies designed to disrupt the financial networks of adversaries and criminal organizations.
His work focused on a wide spectrum of illicit activities, including money laundering, terrorist financing, and the financing of weapons of mass destruction (WMD) proliferation. He was responsible for leveraging U.S. financial tools and sanctions to protect the domestic and international financial systems from abuse.
Leading the Global Fight Against Financial Crime (FATF Presidency)
Billingslea's influence on global financial integrity was magnified during his year as President of the Financial Action Task Force (FATF) from 2018 to 2019. The FATF is the inter-governmental body that sets international standards intended to prevent these illegal activities.
During his presidency, he oversaw efforts to strengthen global anti-money laundering (AML) and counter-terrorist financing (CTF) frameworks, pushing for greater transparency and effectiveness in how countries implement these standards. His leadership helped to focus international attention on emerging threats and jurisdictions that fail to comply with global norms.
Targeting Kleptocracy and Sanctions Enforcement
His Treasury experience also involved direct action against state-sponsored illicit finance. For instance, he has testified before Congress about the financial activities of the Maduro regime in Venezuela, confirming that the regime used illicit financial schemes to maintain power.
This focus on kleptocracy and the use of financial sanctions as a foreign policy tool continues in his current role at the Hudson Institute's Kleptocracy Initiative, where he advocates for policies that combat corruption and the abuse of financial systems by authoritarian regimes.
A Strategic Voice in a New Era of Great Power Competition
Marshall S. Billingslea's career trajectory—from the Pentagon and NATO to the Treasury and State Department—reflects a deep, multi-faceted understanding of U.S. national security priorities. His work during the Global War on Terror provided him with essential experience in combating non-state actors, which he now applies to the more complex challenge of Great Power Competition.
His current role as a Senior Fellow at the Hudson Institute allows him to continue influencing policy by providing expert analysis on the most pressing security challenges of the mid-2020s. Whether it is testifying about the dangers of an unconstrained Chinese nuclear program or advocating for tougher measures against illicit finance, Billingslea remains a pivotal figure. His insights are essential for anyone seeking to understand the intersection of arms control, financial warfare, and the future of global strategy.
