So the principles of warfare are: Do not depend on the enemy not coming, but depend on our readiness against him. Do not depend on the enemy not attacking, but depend on our position that cannot be attacked.
We had to fight the enemy without in the Falklands. We always have to be aware of the enemy within, which is much more difficult to fight and more dangerous to liberty.
You may have enemies whom you hate, but not enemies whom you despise. You must be proud of your enemy: then the success of your enemy shall be your success too.
Your enemy shall ye seek; your war shall ye wage, and for the sake of your thoughts! And if your thoughts succumb, your uprightness shall still shout triumph thereby!
It is the acid test of nonviolence that in a nonviolent conflict there is no rancor left behind, and in the end the enemies are converted into friends.
