"防御上的问题是你能走多远而不从内部摧毁你试图从外部捍卫的东西。"
— Dwight D. Eisenhower
Simplified Meaning:
When you are trying to protect something, you have to be careful not to damage it in the process. Imagine you have a beautiful garden. You want to keep pests away, so you use strong chemicals. These chemicals might kill the pests, but they could also harm the plants you are trying to protect. In the end, the garden could be ruined, not by the pests, but by your own actions. This idea can apply to many areas, like a country trying to protect itself against threats. If a country imposes harsh laws and takes away people's freedoms to feel safe, it might end up destroying the very freedom and way of life it wants to save. It teaches us to find a balance and consider the long-term effects of our protective measures to ensure they do not backfire.
