If your enemy is secure at all points, be prepared for him. If he is in superior strength, evade him. If your opponent is tempermental, seek to irritate him. Pretend to be weak, that he may grow arrogant. If he is taking his ease, give him no rest. If his forces are united, separate them. If sovereign and subject are in accord, put division between them. Attack him where he is unprepared, appear where you are not expected.
I mean, if Pearl Harbor came along, you could have said the planning was wrong by the military ahead of time or maybe the battleships shouldn't have all been in the harbor and all that kind of thing.
Therefore I say: know the enemy and know yourself; in a hundred battles you will never be in peril. When you are ignorant of the enemy but know yourself, your chances of winning or losing are equal. If ignorant both of your enemy and of yourself, you are certain in every battle to be in peril.
So while I will never minimize the costs involved in military action, I am convinced that a failure to act in Libya would have carried a far greater price for America.
The war against Russia will be such that it cannot be conducted in a knightly fashion. This struggle is one of ideologies and racial differences and will have to be conducted with unprecedented, unmerciful and unrelenting harshness.
One of the great things about the United States is that when it comes to world affairs, the president obviously is the leader of the Executive Branch, the Commander-in-Chief, the spokesperson for the nation, but the influence and the work that we have is the result not just of the president, it is the result of countless interactions and arrangements and relationships between our military and other militaries, and our diplomats and other diplomats, the intelligence officers and development workers.
If we know that our own men are in a condition to attack, but are unaware that the enemy is not open to attack, we have gone only halfway towards victory. 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. If we know that the enemy is open to attack, and also know that our men are in a condition to attack, but are unaware that the nature of the ground makes fighting impracticable, we have still gone only halfway towards victory.
We should never hesitate to use military force, and I will not, as president, in order to keep the American people safe. But we have to use our military wisely. And we did not use our military wisely in Iraq.
