本論文試圖解釋菲律賓與美國之間的聯盟政治發展關係。在此發展歷程中，菲律賓有多次離開、並再加入軍事聯盟的紀錄。為了解釋為何身為小國的菲律賓在聯盟政治之表現，本論文採用「新古典現實主義」的觀點認為，在軍事聯盟中，決策者會面臨國家安全與國家自主權的聯盟困境，有時無法兩全，因此決策者的最終決定取決於國際結構的狀態，以及執政者自身受國內政治因素影響的判斷。本論文將採取個案研究方法，並以過程追蹤法來進行檢驗。

This thesis explains the coalition political development relationship between the Philippines and the United States. During this development process, the Philippines has a record of leaving and rejoining military alliances many times. To explain why the Philippines, as a small country, behaves in alliance politics, this paper adopts the viewpoint of "neoclassical realism" and believes that in military alliances, decision-makers will face the alliance dilemma of national security and national autonomy and sometimes cannot. Therefore, the final decision of policymakers depends on the state of the international structure and the judgment of those in power influenced by domestic political factors. This thesis will adopt the case study method and carry on the examination with the method of process tracking.
