We can't, you know, use our military to make sure the planet doesn't get warmer. And so that kind of leadership, of being able to bring people together, to apply practical commonsense solutions based on facts, based on science, based on what works you know, that's been the approach I have taken consistently as a public servant. That's the kind of style that I think we need in the presidency right now.
The art of war teaches us to rely not on the likelihood of the enemy's not coming, but on our own readiness to receive him; not on the chance of his not attacking, but rather on the fact that we have made our position unassailable.
Spies cannot be usefully employed without a certain intuitive sagacity; They cannot be properly managed without benevolence and straightforwardness; Without subtle ingenuity of mind, one cannot make certain of the truth of their reports; Be subtle! be subtle! and use your spies for every kind of warfare; If a secret piece of news is divulged by a spy before the time is ripe, he must be put to death together with the man to whom the secret was told.
Sure I am this day we are masters of our fate, that the task which has been set before us is not above our strength; that its pangs and toils are not beyond our endurance. As long as we have faith in our own cause and an unconquerable will to win, victory will not be denied us.
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.
