“三边安全合作伙伴”（AUKUS）既是美国牵头创设的重要地缘战略工具，也是“后脱欧时代”的英国用以护持、扩展其在“印太”地区国际影响力的重要抓手，是“全球英国”战略构想在一系列实践、试错后，在英国国内政局以及中美、中英关系嬗变等内外因素的综合作用下，最终落地“印太”地区的中间产物。该机制不仅进一步将英国绑上美国遏制中国的战车，也将使英国长期卷入亚太和印度洋地区的安全竞争。它标志着英美澳作为三个具有相同民族血脉与相似战略传统的海权国家谋求在日趋激烈的全球大国竞争中重申“海洋原则”，并以三国海权联盟控扼四大洋，以精炼的“小多边”形式克服“集体行动的困境”，重塑盎格鲁—撒克逊海洋民族全球霸权的内核。故此，美英澳“三边安全合作伙伴”的成立不仅对亚太、印度洋地区的安全秩序造成直接冲击，对全球核不扩散事业构成严峻挑战，而且也深刻影响大国战略关系与世界格局。
AUKUS is not only an important geo-political tool for the US，but also an enabler for the UK to maintain and expand its international influence in the Indo-Pacific region in the post-Brexit era. Thus，AUKUS will further bind the UK to the US’s Indo-Pacific strategy and China policy，and entangle the UK in the security competition of the Asia-Pacific and Indian Ocean region in the foreseeable future. It marks that the US，the UK and Australia，as three major Anglo-Saxon sea-powers with similar strategic traditions，begin to reiterate the “insular principles” and control four oceans（Pacific，Atlantic，Indian，and Arctic）to maintain their Anglo-Saxon global maritime hegemony. Therefore，the establishment of AUKUS may exert a direct impact on the security order in the Asia-Pacific and Indian Ocean region，pose a severe challenge to the global nuclear non-proliferation cause，and make a fundamental change in the strategic relations between major countries and the world order.
