Episode 6 | American Grand Strategy in West Asia
In this episode of Shifting Ground, Nick Gvosdev and Larry Rubin are joined by Mohammed Soliman, Senior Fellow at the Middle East Institute and author of West Asia: A New American Grand Strategy in the Middle East. Soliman challenges our traditional geopolitical mental maps, arguing that the term "Middle East" no longer explains the realities of today’s integrated political and economic landscape. Instead, he proposes viewing the region from the Mediterranean to the Indian Ocean as a single, cohesive space: "West Asia". We dive deep into his thesis on how American grand strategy must adapt to an era where rigid, Cold War-style alliances are giving way to flexible, interest-based "minilateral" coalitions.

Episode 1 : Technology, Trust, and the Accelerants of Global Crisis
Stacey Dixon joins Nick Gvosdev and Larry Rubin to discuss the U.S. government's challenge of balancing national security interests by restricting sensitive technology exports with the need for American companies to compete globally and influence international technology standards.
The conversation highlighted "accelerants" like the democratization of conflict technology and the erosion of public trust due to misinformation, recommending that the government secure critical infrastructure, improve cyber hygiene, and cultivate citizens' digital literacy to counter the negative, unintended uses of emerging technologies.
