The Role of the U.S. in Advancing Stability: China, Africa, and the Long Game
In this episode of The Global Signal, we’re joined by Joseph Schneider, a national security entrepreneur, former U.S. Army Green Beret officer, and strategic advisor with over four decades of experience across the defense, aerospace, and security sectors, to examine how the United States can advance global stability over the long term. The conversation challenges Cold War-style thinking on U.S.–China relations, exploring why collaborative, forward-looking engagement may better serve American interests and what a realistic “win-win” strategy could look like in practice. We then turn to Africa’s rising strategic importance, focusing on the continent’s emerging middle class and its role in shaping America’s future power and influence, before concluding with a discussion of what a credible 30- to 50-year U.S. national strategy would require—and why long-term clarity, rather than reactive policymaking, will define U.S. leadership in the decades ahead.

The Evolution of Warfighting, Deterrence, and Global Security Systems
As global power shifts and emerging technologies erode the boundaries between civilian and military domains, the United States faces a historic inflection point. Traditional models of deterrence, once defined by nuclear posture and military might, are being challenged by autonomous systems, contested orbital space, cyber warfare, and the weaponization of critical infrastructure.In this episode of The Global Signal, Joshua Charles sits down with Benjamin Njila Fields, a leading thinker at the intersection of defense innovation and strategic policy, to map the future of American deterrence. Together, they explore the rise of dual-use technologies, the evolving role of the private sector in national security, and how the United States must adapt to maintain stability in an increasingly multipolar world.This conversation is not about predicting conflict. It is about understanding the systems that prevent it. If you care about the future of American power, technology, and the global order, this is an episode you cannot miss.
