NOT TO GET ALL HUNG UP about the civilian leadership of the U.S. Navy – but people keep pointing out odd things to us. Earlier we noted press reports that the Secretary of Defense/War Pete Hegseth fired the civilian chief of staff to the Secretary of the Navy. It seemed odd that – if firing were merited – the Secretary of the Navy John Phelan wasn’t the guy to do it.

As tensions rise globally, so does the risk of conflict. Poland’s Prime Minister has recently warned that Poland is closer to war than at any time since WWII. And while Russia’s war against Ukraine escalates with no clear path to peace in sight, other incidents such cyberattacks and drone incursions across NATO airspace are fueling growing uncertainty among European leaders.

At the same time, U.S.–China competition is intensifying across economic, military, and technological fronts with some arguing that the risk of military conflict between Washington and Beijing is rising. But some experts argue the U.S. is already engaged in a “Gray War” with Beijing - without realizing it.

In this episode of The State Secrets Podcast, guest host Brad Christian speaks with former CIA officers Dave Pitts and Chip Usher, authors of a recent Cipher Brief article called China’s Gray War on America. Together, they unpack Beijing’s doctrine of “Unrestricted Warfare,” explore the six strategic fronts of China’s current strategy against the U.S., and assess America’s vulnerabilities and options. From the fight for AI supremacy to the dangers of strategic defeat, this conversation is a must-listen for anyone concerned with the future of U.S. power and security.
