At the 2025 Taipei Security Dialogue, former Australian Prime Minister Scott Morrison underscored that the security threat to Taiwan is no longer a regional issue but one with global ramifications. In his keynote speech, former PM Morrison warned that if Taiwan were forcibly subjected to the authoritarian rule of the Chinese Communist Party (CCP), no part of the world would be immune to the impact. He emphasized that maintaining the status quo in the Taiwan Strait is essential for the security, prosperity, and sovereignty of many nations, including Australia, the United States, and Japan.

He analyzed that should the First Island Chain, Taiwan's defense line, fall, the U.S. would be pushed back to the Second Island Chain (Guam, Palau, etc.), significantly weakening its capacity to serve as an effective security counterbalance in the Indo-Pacific region. This would allow the Chinese People’s Liberation Army (PLA) to project its air, naval, and missile surveillance capabilities into the Philippine Sea via the Bashi Channel and the Miyako Strait, meaning regional maritime and air traffic would pass through boundaries and airspace under Chinese control.

To prevent such a scenario, former PM Morrison urged democratic nations worldwide to strengthen their collective deterrence through new initiatives and collaborations such as AUKUS (Australia, U.K., U.S. security partnership).

Experts attending the forum emphasized the importance of Taiwan's self-defense efforts and preparation for modern warfare. Matt Schlapp, Chairman of the American Conservative Union, stated that the U.S. now views the Beijing regime as an existential threat to freedom and trade, even more so than Russian President Vladimir Putin, and that strong American leadership is crucial for Taiwan's security.

Van Hipp Jr., former U.S. Deputy Assistant Secretary of the Army, suggested that as cyber warfare evolves into the 'Fifth Battlefield,' Taiwan could significantly boost its military autonomy and responsiveness by investing in a 'smart network' that integrates Artificial Intelligence (AI) and unmanned platforms. Former UK Rear Admiral Peter Olive highlighted the difficulty of a landing operation on Taiwan, and Philip Shetler-Jones, Senior Research Fellow at the Royal United Services Institute (RUSI), emphasized the importance of a deterrence goal that makes any enemy invasion meaningless, citing the example of Ukraine. He proposed considering a strategy of counter-blockading Chinese vessels far from Taiwan, such as in the Indian Ocean, to counter China's anticipated efforts to erode Taiwan's social resilience through cyber warfare, economic coercion, and limited blockades.

Huo Shou-Yeh, Chairman of the Institute for National Defense and Security Research (INDSR) in Taiwan, concluded that given that peace in the Taiwan Strait is now a global concern, integrating the deterrence capabilities of regional actors and like-minded nations is key to maintaining peace and democracy in the Indo-Pacific. Taiwan's stance is that it does not seek provocation or hostility but is demonstrating the capacity to provide effective deterrence.
