美国关于安全战略、世界力量划分和对外政策的新调整

The US security strategy, world power differentiation and foreign policy: a new adjustment

美国认定，２０１５年前不受任一大国的直接军事威胁，无主要对手，但面临现实的非对称性威胁，亦即恐怖主义、极端民族主义和电子黑客的威胁。现有军事联盟的作用相对下降。美国正以是否属于世界稳定力量作为划分世界力量的主要标准，力求逐步扩大运用融合战略。对中国的中近期定位是：非敌人，非主要对手，主要新兴大市场。

Abstract The US maintains that no major power will be able to pose direct military threats on the US before 2010, but the US is confronted with realistic non symmetric threats terrorism, ultranationalism and hackers. The role of existing military alliance is relatively declining. The US is taking a major criterion whether it belongs to a power for world stability to differentiate pwoers in the world and endeavors to gradually expand and adopt engagement strategy. The US medium and long term assessment of China is that China is a non enemy,non major rival. China is a emerging major market and quasi partner of strategy.
