Taiwan does not exist in a state of true peace. Its situation is more akin to a prolonged, unofficial state of political warfare. The Legislative Yuan, beyond being the venue of policy debate in Taiwan, has become the front line of resistance in the conflict. Understanding this strategic reality is crucial to understanding the amendments to the Act Governing Relations Between the People of the Taiwan Area and the Mainland Area (臺灣地區與大陸地區人民關係條例), which require legislators to obtain approval before traveling to China.
In his book On War, Prussian military theorist Carl von Clausewitz wrote that “war is the continuation of policy by other means.” The threat of military force has long ceased to be all Taiwan faces — political engagement, infiltration and psychological manipulation have steadily eroded Taiwan’s defenses. This is the essence of political warfare: influencing a society’s decisions without ever firing a shot.
A series of espionage cases uncovered this year are concrete examples of this kind of political warfare. From military personnel being influenced into changing their stance on defense to former staff members of the Presidential Office and the Ministry of Foreign Affairs being suspected of leaking classified information, these cases of infiltration are far from isolated incidents. They are the product of long-standing institutional vulnerabilities being repeatedly exploited.
The front line of this battle runs not along the middle of the Taiwan Strait, but right through the corridors of executive power and governance.
Another core theme of On War is the concept of a “center of gravity,” or the primary source of strength, will or stability of a military force, which, if targeted effectively, would cripple its ability to fight. Taiwan’s center of gravity is not any individual military asset, but its democratic credibility, parliamentary legitimacy and public trust in the nation’s will to defend itself.
Legislators control defense budgets, national security legislation, and have access to classified briefings. Their contact with foreign actors is of utmost strategic sensitivity. If legislators’ travel to China continues to lack oversight and transparency, it would leave a gap in the defenses against political warfare. Once the legislature’s external engagements become channels that hostile forces can exploit, democratic institutions risk being stripped of any meaningful autonomy, despite their external form appearing to remain intact.
The point of the legal amendments to the cross-strait act is not to cut off all exchanges, but to raise the cost of infiltration by requiring prior approval, full disclosure of activities, and imposing penalties for violations. If political infiltration is to be prevented, it can no longer be a zero-risk endeavor. The amendment is not a turn to authoritarianism, but a practical step toward defensive democracy. The regulations specifically target elected officials who hold power and access to classified information, not ordinary citizens.
Exchanges may continue, but the exercise of power must take place in the light of day. Only with transparency and accountability can institutions meaningfully serve as safeguards of democracy, rather than shackles.
Clausewitz warned that one of the greatest mistakes is to act on a false assumption of peace. In light of infiltration taking place through institutional channels, these legal amendments are not an overreaction; they are an acceptance of reality and a step toward patching vulnerabilities. In an era of authoritarian expansion, not pursuing a defense strategy would not be tolerance, but a dereliction of duty. Taiwan must make itself absolutely clear: We understand our position on the battlefield and we choose to defend our way of life through the rule of law and transparency.

In the US’ National Security Strategy (NSS) report released last month, US President Donald Trump offered his interpretation of the Monroe Doctrine. The “Trump Corollary,” presented on page 15, is a distinctly aggressive rebranding of the more than 200-year-old foreign policy position. Beyond reasserting the sovereignty of the western hemisphere against foreign intervention, the document centers on energy and strategic assets, and attempts to redraw the map of the geopolitical landscape more broadly. It is clear that Trump no longer sees the western hemisphere as a peaceful backyard, but rather as the frontier of a new Cold War. In particular,
When it became clear that the world was entering a new era with a radical change in the US’ global stance in US President Donald Trump’s second term, many in Taiwan were concerned about what this meant for the nation’s defense against China. Instability and disruption are dangerous. Chaos introduces unknowns. There was a sense that the Chinese Nationalist Party (KMT) might have a point with its tendency not to trust the US. The world order is certainly changing, but concerns about the implications for Taiwan of this disruption left many blind to how the same forces might also weaken
As the Chinese People’s Liberation Army (PLA) races toward its 2027 modernization goals, most analysts fixate on ship counts, missile ranges and artificial intelligence. Those metrics matter — but they obscure a deeper vulnerability. The true future of the PLA, and by extension Taiwan’s security, might hinge less on hardware than on whether the Chinese Communist Party (CCP) can preserve ideological loyalty inside its own armed forces. Iran’s 1979 revolution demonstrated how even a technologically advanced military can collapse when the social environment surrounding it shifts. That lesson has renewed relevance as fresh unrest shakes Iran today — and it should
As the new year dawns, Taiwan faces a range of external uncertainties that could impact the safety and prosperity of its people and reverberate in its politics. Here are a few key questions that could spill over into Taiwan in the year ahead. WILL THE AI BUBBLE POP? The global AI boom supported Taiwan’s significant economic expansion in 2025. Taiwan’s economy grew over 7 percent and set records for exports, imports, and trade surplus. There is a brewing debate among investors about whether the AI boom will carry forward into 2026. Skeptics warn that AI-led global equity markets are overvalued and overleveraged
