If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.
We're certain there are people that can't stand what America stands for... We're certain there are madmen in this world, and there's terror, and there's missiles and I'm certain of this, too: I'm certain to maintain the peace, we better have a military of high morale, and I'm certain that under this administration, morale in the military is dangerously low.
The President does not have power under the Constitution to unilaterally authorize a military attack in a situation that does not involve stopping an actual or imminent threat to the nation.
Bestow rewards without regard to rule, issue orders without regard to previous arrangements; and you will be able to handle a whole army as though you had to do with but a single man.
Teller contended, not implausibly, that hydrogen bombs keep the peace, or at least prevent thermonuclear war, because the consequences of warfare between nuclear powers are now too dangerous. We haven't had a nuclear war yet, have we? But all such arguments assume that the nuclear-armed nations are and always will be, without exception, rational actors, and that bouts of anger and revenge and madness will never overtake their leaders (or military and secret police officers in charge of nuclear weapons). In the century of Hitler and Stalin, this seems ingenuous.
Military necessity does not admit of cruelty - that is, the infliction of suffering for the sake of suffering or for revenge, . . . nor of torture to extort confessions.
The solution to Iraq - an Iraq that can govern itself, sustain itself and defend itself - is more than a military mission. Precisely the reason why I sent more troops into Baghdad.
