Ray and Jim welcome AEI senior fellow Zack Cooper to the podcast to discuss China's increasingly aggressive behavior, and what the U.S. and its allies need to do in response. They focus on the question of how deterrence strategies need to evolve and adapt to the threats, whether they be nuclear, conventional military, or across the spectrum of malign gray-zone activities. They discuss the specific need to deter a military move against Taiwan. The discussion turns to the topic of extended nuclear deterrence, and whether a perceived U.S. inability or unwillingness to back up its security guarantees might lead its allies in the region to pursue their own nuclear weapons programs and lead to a breakdown of the non-proliferation regime. Zack also covers the recent U.S. policy of “integrated deterrence” and whether it can be effective, as well as recent discussion about an “Asian NATO” and whether it has a future.
