特魯尼赫特綜合症與魯比奧學說 — 參與的終結

The Rubio Doctrine represents a significant shift in US foreign policy, moving away from the previous engagement strategy focused on integrating China into the global system. Instead, it operates on the premise that engagement has failed, advocating for a systemic decoupling from China to prioritize domestic security and economic stability.

The 2025 National Security Strategy emphasizes that economic security is integral to national security, marking a departure from the free trade model of the 1990s. This strategy identifies vulnerabilities in supply chains as national security threats, prompting the US to focus on reshoring critical industries and fortifying domestic production capabilities.

In 2026, the US has shifted its military strategy in the Taiwan Strait from a focus on political presence to combat readiness. This involves decreasing transit frequency of Aegis destroyers and prepositioning long-range missiles in the Philippines and Japan to create a strategy of denial, ensuring the US is prepared for potential conflicts while minimizing overt displays of military power.

The 'Porcupine' strategy entails arming Taiwan with asymmetric weapons to enhance its defensive capabilities, signaling a commitment to help Taiwan maintain its sovereignty. However, it also indicates a shift in US policy, suggesting that while the US will assist in defense, it will no longer rely on Taiwan's stability for its own national security.

The conclusion indicates a transformative approach in US foreign policy, where reliance on the goodwill of allies and a globalized supply chain is no longer viable. Instead, the US is focused on building its own defenses and supporting allies like Taiwan, reflecting a more cautious, self-reliant stance in the face of global tensions.
