Have you ever played a purely defensive game of chess? Not a perfect analogy, of course, yet a good demonstration that your opponent will eventually get in. You only have to make one mistake and you have nothing to counter with. In that context (chess) the final evaluation reveals a well executed attack is superior to a defensive stance. I suspect the same is true of espionage and war. In other words, stop them before they have the opportunity to get to your king. Another hypothetical: Imagine a future event when, for whatever reason, a band of twenty criminals is intent on breaking into one hundred homes in your neighborhood. The twist is: You can’t call the police for help. Which decision would lead to securing these homes: Each family stays in their home to defend it or one hundred neighbors join forces to repel them?
