Episode 9 asserts that a nation unable to defend itself cannot lead effectively. It describes how decades of misguided foreign interventions, poor domestic defense strategies, and a decline in manufacturing have weakened America’s global standing. Adversaries such as China and Russia exploit these vulnerabilities, posing threats to national security and American economic independence. Key challenges include an aging military, recruitment shortfalls, and overreliance on foreign supply chains. The chapter advocates a comprehensive approach: rebuild military readiness, fortify borders, achieve energy independence, and strengthen industrial capacity. Ultimately, it contends that national security is foundational to maintaining leadership and protecting American interests.
