War should be the only study of a prince. He should consider peace only as a breathing-time, which gives him leisure to contrive, and furnishes as ability to execute, military plans.
If asked how to cope with a great host of the enemy in orderly array and on the point of marching to the attack, I should say: "Begin by seizing something which your opponent holds dear; then he will be amenable to your will." Rapidity is the essence of war: take advantage of the enemy's unreadiness, make your way by unexpected routes, and attack unguarded spots.
It is characteristic of the military mentality that non-human factors ... are held essential, while the human being, his desires and thoughts-in short, the psychological factors-are considered as unimportant and secondary.
You bomb ISIL. You're not trying to bomb innocent people. And that requires intelligence and confidence in our military to be able to develop the kinds of targets that we need. We're already doing Special Forces, who are going to help us gather that intelligence and help advise and assist and train local forces so that they can go after ISIL in areas like Raqqah and Mosul.
Arm yourselves, and be ye men of valor, and be in readiness for the conflict; for it is better for us to perish in battle than to look upon the outrage of our nation and our altar.
Air power can either paralyze the enemy's military action or compel him to devote to the defense of his bases and communications a share of his straitened resources far greater that what we need in the attack.
I have made it a top priority for my administration to deepen cooperation with Israel across the whole spectrum of security issues - intelligence, military, technology.
