One bleeding-heart type asked me in a recent interview if I did not agree that 'violence begets violence.' I told him that it is my earnest endeavor to see that it does.

By doing what our assailant least expects us to do, we may throw him completely off. ... what he usually least suspects is instant, violent counterattack, so the principle of aggressiveness is closely tied to threat of surprise.
