摘要：

美國例外論建立在其硬實力與自由民主價值觀之上；支持台灣對抗中國則是在考驗這個理念。然而，川普以交易為導向的外交政策削弱了美國的偉大，如今又面對與中國的地緣政治競爭，甚至逐漸漠視台灣安全。 

  • 台灣對美中兩國來說都具有經濟與安全上的關鍵意義。然而，台灣在意識形態上與更契合美國，且更具戰略價值，使得台灣成為檢驗美國例外論的重要場域。 
  • 台灣的科技產業，尤其是先進製程半導體與其他高科技產品，對美國經濟至關重要。雖然美國積極推動半導體供應鏈多元化，但由於台灣本土規範要求企業至少保持一個世代的技術領先地位，台灣將保有不可取代的角色。若中國執意武力犯台，將造成比 COVID-19 疫情更嚴重的全球經濟災難。 
  • 基於台灣對美國經濟的重要性，美國必須維持在印太地區及第一島鏈的實體安全存在，以確保與台灣的經濟聯繫。 
  • 美國自己必須具備可靠的軍事能力與誠信，方能建立堅固的同盟與夥伴關係。歷屆美國政府都曾展現對台灣安全的承諾，包括對台軍售、強化與印太夥伴的安全協議，以及維持在西太平洋的前線部署。 
  • 若現任政府持續聚焦經濟利益而忽視整體戰略利益，其他國家將對美國實力失去信心。同時，美國的對手將利用其弱點，在區域建立霸權或進一步削弱美國影響力。因此，美國應捍衛台灣的自治權，以證明美國例外論依然存在。 
 
Summary: 
American exceptionalism is built on its hard power and liberal democracy values; supporting Taiwan against Chinese hostility is a test of it. However, Trump's transactional approach to foreign policy undermines the US's greatness, especially in the midst of a geopolitical competition with China and increasing ignorance of Taiwan's security. 
  • Taiwan is crucial for both China and the US for economic and security reasons. However, Taiwan is more ideologically compatible and strategically valuable for the US, making it more significant for the US to test its exceptionalism. 
  • Taiwan's technology sector, particularly its advanced-node semiconductor and other high-technology products, is vital to the US economy. Despite efforts to diversify the semiconductor supply chain, Taiwan will remain critical because domestic regulations require its firms to stay at least one generation ahead. If China invades the island, it will cause a global economic catastrophe worse than the COVID-19 pandemic. 
  • Given the importance of Taiwan to the US economy, the US must retain its physical security presence in the Indo-Pacific region, especially in the first island chain, to sustain its economic ties with Taiwan. 
  • The US itself must have reliable military capabilities and credible integrity to form sturdy alliances and partnerships. Former US administrations have demonstrated a commitment to Taiwan's security by selling arms to Taiwan, fostering stronger security agreements with Indo-Pacific partners, and maintaining some forward presence in the Western Pacific.  
  • If the current administration continues to focus on its economic interests while ignoring the overall strategic interests, other countries will lose faith in the US power. Furthermore, US adversaries will exploit its weaknesses to establish regional dominance or further undermine its power. Therefore, the US should protect Taiwan's self-governance to prove that American exceptionalism has not died.
