Taiwan’s Security Uncertainty and Response Strategy Under the Second Trump Administration

This study analyzes Taiwan’s strategic responses amid growing US–China tensions and increasing cross-Strait instability. As China intensifies its military and political pressure, Taiwan faces the dual challenge of strengthening its self-defense capabilities while sustaining international support. The potential return of a transactional US administration raises concerns about reduced security guarantees. Taiwan must enhance its asymmetric defense strategies, expand diplomatic networks beyond the US, and diversify its semiconductor and supply chains to bolster resilience. Simultaneously, it must carefully manage its relations with China to avoid unnecessary provocation, while reinforcing domestic political stability and societal preparedness. This multidimensional strategy is essential to deter aggression, safeguard democratic values, and maintain regional stability.
