Retired U.S. Marine Colonel Grant Newsham is a senior fellow with the Center for Security Policy, as well as a research fellow at the Japan Forum for Strategic Studies focusing on Asia/Pacific defense, political, and economic matters. We discuss the implications of Japan making it clear that the Chinese Communist Party attacking Taiwan is equal to attacking Japan. We explore what it means regarding Japanese defense capabilities, how the United States might respond, and how China might treat this change. We also discuss what Mr. Newsham thinks will be the future of the U.S.–China relationship. Is it a toss-up over who can win? Or is it a one-sided victory?
