The security dilemma is a fundamental feature of international politics, as states' efforts to increase their own security often decrease the security of others.

A sound mind in a sound body, is a short, but full description of a happy state in this World: he that has these two, has little more to wish for; and he that wants either of them, will be little the better for anything else. Men’s happiness or misery is most part of their own making. He, whose mind directs not wisely, will never take the right way; and he, whose body is crazy and feeble, will never be able to advance in it.

一切都是旧的。没有别的。曾经尝试过，曾经失败过。没关系。再试一次。再失败一次。失败得更好一点。

The best solutions are often the simplest ones.
