美国学者鲁思·本尼迪克特曾写过一本名叫《菊与刀》的书,描述日本民族的双重性格,本文标题借用这一形式,并改为《盾与刀》,讲的是日本极力发展的、具有双重作用的弹道导弹防御系统。 American scholar Ruth Benedikt once wrote a book titled “The Chrysanthemum and the Knife,” which describes the dual personality of the Japanese nation. The title of this article borrows from this form and replaces it with “shield and knife”, referring to Japan Strongly developed ballistic missile defense system with dual functions.
