‘Yes, the defence.’ He didn’t repeat the whole phrase, perhaps because it suddenly sounded too pompous. ‘Just as happens in land battles and naval battles and bombardments that no one foresees or expects. Do you really imagine that they involve no deceit, no treachery? There’s something called “strategy” and another thing called ”tactics” and what’s fundamental to both is the surprise factor, the ambush, the diversionary manoeuvre, camouflage, pretence, concealment, the perfidy you find so reprehensible. Why do you think there are submarines, for heaven‘s sake? They’re invisible, right? And there must be some reason for that, don't you think? Even at Thermopylae there was an infiltrator, or a traitor, if you prefer. And how do you think the Trojan War was won? What else was that horse but a stratagem, a poisoned chalice, a deceit? The people who left it on the beach were not to blame, but those who dragged it into the city. The tricked are to blame, not the tricksters, because the latter are just doing their duty. Both sides know this and both sides are to blame. You have to be duplicitous in war, that’s how wars are fought.’引自第286页
