後安倍時期日本島鏈防衛力整備的戰略設計──以日本增強西南群島飛彈防禦能力觀察其離島防衛體系的變化

Strategic conception of Japan’s island chain defense capabilities in the post-Abe period: Observe the changes in Japan’s outlying island defense system by enhancing its missile defense capabilities in the Southwest Islands

無論是中國不斷擴張軍力，形成對東亞地緣政治在軍事與安全的威脅壓力升高情勢，或是安倍前首相一句「台灣有事就是日本有事也就是日美同盟有事」的反制論點，至今仍被日美中台各方學界或是政界高度關注，甚至出現「海權論」或「邊緣地帶論」等地緣政治理論，競相成為智庫或者學界研究全球戰略或是印太區域安全議題關注的焦點。
顯然日本早已認知到即使美中衝突或台海危機，幾乎不可能置身事外。無論日本方面採取何種安保體制的調整與修訂，無疑都在「想定萬一」被捲入美中兩大國在東亞第一島鏈地緣政治的軍事衝突當中，那麼日本如何思考自身在國際政治與地緣政治應扮演的角色？然，這是否意謂著後安倍時代日本已然改變自二戰以來堅持多年的和平主義路線？關於新安保法的內容在法規範上應如何正確解讀？而從日本強化「增程型12式地對艦誘導彈」戰力一事，觀察其在東亞第一島鏈地緣政治的衝突當中，如何增強西南群島飛彈防禦體系的變化？等重要安保體制等課題，本文將進行深入的分析與檢討。

Whether it is China’s continuous expansion of military power, which poses an increasing threat to East Asia’s geopolitics in terms of military and security pressure, or former Prime Minister Abe’s counterargument that“if Taiwan is in trouble, Japan is in trouble, and the Japan-US alliance is in trouble,”it is still being criticized to this day. The academic or political circles in Japan, the United States, China and Taiwan are paying close attention to it, and geopolitical theories such as“sea power theory”or“marginal zone theory”have even emerged, competing to become the focus of think tanks or academic circles studying global strategy or security issues in the Indo-Pacific region.
Obviously, Japan has long realized that even if there is a conflict between the United States and China or a crisis in the Taiwan Strait, it is almost impossible to stay out of it. No matter what adjustments and revisions Japan adopts to its security system, it is undoubtedly“in case”it is involved in the geopolitical military conflict between the United States and China on the first island chain in East Asia. So how does Japan think about its role in international politics and What role should geopolitics play? However, does this mean that in the post-Abe era Japan has changed the pacifist line it has adhered to for many years since World War II? How should the content of the new security law be interpreted correctly in terms of legal norms? From Japan’s strengthening of the combat capabilities of the“Extended Range Type 12 Surface-to-Ship Guided Missile”, observe how it will enhance the changes in the missile defense system of the Southwest Islands amid the geopolitical conflict on the first island chain in East Asia. This article will conduct in-depth analysis and review of important security system and other issues.
