Gioe is British Academy Global Professor and Visiting Professor of Intelligence and International Security in the Department of War Studies at King’s College London and Director of Studies for the Cambridge Security Initiative and is co-convener of its International Security and Intelligence program. He joins host Krys Boyd to explain what an “intelligence liaison” is and why the U.S. has broken those unwritten rules, and why that might put our national security in a precarious position. His article “How America’s Allies Boost U.S. Intelligence” was published in Foreign Affairs.
