Niccolò Machiavelli on war and peace

Rome remained free for four hundred years and Sparta eight hundred, although their citizens were armed all that time; but many other states that have been disarmed have lost their liberties in less than forty years.

Occasionally words must serve to veil the facts. But this must happen in such a way that no one becomes aware of it; or, if it should be noticed, excuses must be at hand, to be produced immediately.

There are three kinds of intelligence: one kind understands things for itself, the other appreciates what others can understand, the third understands neither for itself nor through others. This first is excellent, the second good, and the third useless.

The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

• Liberty

Every gun that is made, every warship launched, every rocket fired, signifies in the final sense a theft from those who hunger and are not fed, those who are cold and are not clothed.

• Guns

The object of war is not to die for your country but to make the other bastard die for his.

George S. Patton1885–1945
