Through historic analysis and comparison, this paper disapproves of obstinate realism as well as naive neoliberalism, but holds in esteem an experienced and prudent defensive realism with flexibility, which could give us some useful guidance on security strategy of our country. 本文不赞成固执僵化的现实主义,同时亦不赞成天真的新自由主义,而是较为推崇老成持重却又不失灵活的防御性现实主义,认为它能够为崛起的中国提供某些安全哲学。
