美中介入與反介入戰略是建在兩條島鏈基礎上。為反制崛起中國，美國重返亞洲要點是重建亞太島鏈地緣政治。反介入與區域阻絕是西方術語，中國類似詞語是積極的戰略外線反擊作戰。近來中國導彈對周邊國家構成威脅，水面艦與潛艦頻繁穿越沖繩海域。台灣位居第一島鏈關鍵地緣戰略位置，可將中國海空力量困在第一島鏈。在美國建構自身的反介入與區域阻絕能力同時，台灣需要一支反介入力量並配合美國重返亞洲政策。

Washington’s and Beijing’s access and anti-access strategies are constructed on the basis of two island chains. In order to countervail a rising China, the essence of the U.S. Asia pivot is reviving again the geopolitics of the Western Pacific. The term of A2AD is a Western terminology and its approximation in the Chinese strategic concept is China’s active strategic counterattacks on exterior lines (ASCEL) and today China’s A2AD capabilities have increased dramatically. China’s missile arsenal constitutes severe threats to its neighboring countries, and its surface warships and submarines have frequently penetrated the Ryukyu Islands. Due to its position in the center of the first island chain, Taiwan is of great geostrategic importance. It is the cork that keeps the Chinese naval and air forces bottled up within the China Sea. One simple option for the U.S. and its partner nations to counter Beijing’s increasing military strength is to boost their own version of A2AD capability. Taiwan should reshape its force structure with a strategy of asymmetry, combat credibility and resilience, as well as cooperating with the U.S. Asia pivot.
