The Emerging Potential for Quantum Computing in Irregular Warfare

Quantum computing represents a paradigm shift in computational technology, poised to revolutionize industries including national security and defense. While the abilities of quantum computing still remain largely theoretical, significant progress is being made. Notably, experiments from companies like Google and IBM have demonstrated early examples of quantum supremacy, where quantum computers outperform classical systems on specific tasks. These breakthroughs suggest that quantum computing is not only on the horizon but is considered an inevitable advancement that stakeholders should prepare for now.

OSS 2.0: Emphasizing the Importance of Human Intelligence in Irregular Warfare for Great Power Competition

As the global landscape shifts into an era of Great Power Competition, characterized by unconventional threats and complex geopolitical dynamics, the need for a reimagined Office of Strategic Services (OSS) framework has never been more pressing. The revival of an OSS 2.0 would empower the Department of Defense (DoD) with enhanced Human Intelligence (HUMINT) capabilities that are critical for navigating the intricacies of Irregular Warfare (IW). Leveraging an updated OSS concept, the DoD could build deeper, longer-lasting relationships with foreign partners and local populations, laying the foundation for invaluable intelligence collection and clandestine or covert operations.

The Role of Non-State Actors as Proxies in Irregular Warfare and Malign State Influence

This paper explores the ways that states benefit from the activities of non-state actors (NSAs) as tools of irregular warfare (IW), with a particular focus on China and Russia. An examination of the historical relationships between state and non-state actors reveal that while proxies provide many potential advantages to their authoritarian patrons, they also present significant problems. The paper further demonstrates how China and Russia each utilizes a wide range of NSAs in a similarly broad spectrum of irregular warfare activities, including low-level persistent operations designed to erode adversaries’ institutions over time, to much more kinetic operations that directly challenge the territorial integrity of other sovereign states. Implications for how to respond to these activities are discussed.
