The Great War differed from all ancient wars in the immense power of the combatants and their fearful agencies of destruction, and from all modern wars in the utter ruthlessness with which it was fought... Europe and large parts of Asia and Africa became one vast battlefield on which after years of struggle not armies but nations broke and ran. When all was over, Torture and Cannibalism were the only two expedients that the civilized, scientific, Christian States had been able to deny themselves: and they were of doubtful utility.
As you travel through the Middle East what keeps on striking home to me is how similar everyone is, and yet the degree to which we can find differences to fight wars over. It requires a great deal of empathy, I think, between various sides to overcome this history and live in peace.
The story of the human race is war. Except for brief and precarious interludes there has never been peace in the world; and long before history began murderous strife was universal and unending.
If we know that the enemy is open to attack, but are unaware that our own men are not in a condition to attack, we have gone only halfway towards victory.
It boils down to this: we should have done with humbug, and let war be war, and not a game ... If there were none of this magnanimity business in warfare, we should never go to war, except for something worth facing certain death for.
