Experience demonstrates the dangers that can arise when vulnerable powers act independently. One need look no further than Israel, with its penchant for overreaction on security matters, or Iran, with its insistence on enriching uranium, to see what can happen when an isolated power bases its actions on a sense of existential vulnerability.
经验表明，当弱势权力独立行动时会产生危机。不用想得太远，从以色列在安全问题上的过度反应，或是伊朗在铀浓缩问题上的坚持，就能看到一个孤立的政权在刚愎自用的基础上行动可能会导致何种状况。
