If we are willing to act violently in pursuit of a peripheral interest, everyone can be certain that, when a vital interest is at stake, we will be still more violent. 'Credibility' is defined as the willingness to kill a lot of people now for a not very good cause to assure the world that we'll kill a lot more people if we can find a better one.
I wanted to be born at the farthest limit of the world. I'll explore it, I said to myself, biting big chunks from it. And when I want, I'll go straight to the core. This is the way of the world I thought in my innocence, round and around the layers of peel until the taste becomes certain.
It's always easy to blame others. You can spend your entire life blaming the world, but your successes or failures are entirely your own responsibility.
