Amidst international geopolitical turbulence, U.S. President Donald Trump recently expressed strong dissatisfaction with Ukrainian President Volodymyr Zelenskyy, publicly advocating that Ukraine should elect a leader more capable of reaching an agreement with Russia. This move is viewed as a significant shift in U.S. foreign policy, not only directly challenging Ukraine’s political autonomy but also triggering widespread global debate regarding U.S. policies on supporting long-term allies.

Simultaneously, the situation in the Middle East has fallen into extreme instability. Since the end of February this year, Iran has launched ballistic missile attacks against Persian Gulf nations and U.S. military bases in the region, resulting in significant casualties within Israel. Furthermore, the civil war in Yemen, following a Houthi offensive launched in September, has evolved into a chain reaction of transnational conflict, exacerbating the displacement crisis within the region.

According to cross-referenced reports from multiple media sources, Trump’s public pressure on the Ukrainian leadership has become a focal point of international public opinion. U.S.-based professor Weng Lu-chung analyzed that Trump’s remarks symbolize that the U.S. is rewriting the global definition of "American support," emphasizing that the nature of U.S. commitments is deeply tied to realistic interests. On another front, the deterioration of the situation in the Middle East has been confirmed by multiple parties. According to The Jerusalem Post, since February 28, 2026, ballistic missile attacks launched by Iran have killed 19 civilians and 2 Israel Defense Forces (IDF) soldiers, with at least 4,002 others injured and 11 U.S. soldiers killed in the conflict.

The UN News Centre has also confirmed that after 12 years of civil war in Yemen, the spillover effects of the U.S.-Iran conflict have led to a new wave of humanitarian disasters and displacement crises, with the Security Council recently convening an emergency meeting to discuss the situation.

Although reports from all sides point to rising geopolitical tensions, there are still discrepancies in the details. Regarding Trump’s remarks, media focus has primarily been on his interference in Ukraine’s political leadership and the potential warning it serves to allies such as Taiwan; however, there remains room for interpretation regarding the specific diplomatic strategy behind Trump’s actions. Regarding the war in the Middle East, while The Jerusalem Post provided specific casualty figures, different sources vary in their focus on the path of further escalation and the details of the military standoff between Iran and the U.S. in the region.

Information from the United Nations focuses more on the long-term impact and humanitarian consequences of the Yemeni civil war, while there are time lags and differences in statistical scope compared to the real-time updates provided by regional media regarding specific military casualties.

These geopolitical shifts have had a direct and profound impact on global industries, policies, and social stability. For Taiwan, the "greatest warning" emphasized by U.S.-based scholars is that Taiwan cannot rely solely on unilateral support from the U.S. and must possess the ability to survive autonomously should U.S. interests shift. This uncertainty has begun to affect global supply chains and security expectations. In the Middle East, ongoing ballistic missile attacks not only threaten the security of energy transport but also hinder the operations of military bases in the region, thereby triggering potential volatility in global energy markets.

The displacement crisis in Yemen poses a severe challenge to social stability and public health in neighboring areas, and the United Nations has repeatedly called on the international community to pay attention to the increasingly deteriorating living conditions there.

However, interpretations of the aforementioned events should not be overly simplified. While Trump’s remarks on Ukraine have caused tremors, whether they represent a final U.S. withdrawal of support for Ukraine remains to be seen through the actual policy implementation of the U.S. Congress and diplomatic departments. Similarly, while the deterioration of the Middle East situation is severe, the specific strategic goals and negotiation bottom lines of the various parties involved in the conflict have not yet been fully clarified. While drawing a direct analogy between the Ukraine issue and Taiwan’s situation provides a perspective for policy reflection, the two differ fundamentally in geography, international legal status, and geostrategic value; over-interpretation may overlook the complexities of international relations.

When conducting analysis, all parties should maintain a cautious attitude toward information sources and avoid treating the remarks of a single political figure or data from a regional battlefield as a final conclusion.

Subsequent observations will focus on the U.S. government’s specific actions regarding the Ukraine issue and how the Zelenskyy administration responds to political pressure from Washington. In the Middle East, whether the international community can effectively mediate the Yemen conflict through UN mechanisms, and whether the military standoff between the U.S. and Iran in the Persian Gulf will further expand, will be key factors affecting global security. Additionally, how the Taiwan government adjusts its national defense autonomy and diplomatic strategies in the face of drastic changes in the international geopolitical environment to cope with a potential "realist" shift in U.S. policy will be a focus worth tracking in the coming months.
