War is mainly a catalogue of blunders.
You don't reason with intellectuals. You shoot them.
Civil war? What does that mean? Is there any foreign war? Isn't every war fought between men, between brothers?
War is over ... If you want it.
As soon as men decide that all means are permitted to fight an evil, then their good becomes indistinguishable from the evil that they set out to destroy.
There is a road from the eye to the heart that does not go through the intellect.
A person may cause evil to others not only by his actions but by his inaction, and in either case he is justly accountable to them for the injury.
Never forget that everything Hitler did in Germany was legal.
Never think that war, no matter how necessary, nor how justified, is not a crime.
War is an ugly thing, but not the ugliest of things. The decayed and degraded state of moral and patriotic feeling which thinks that nothing is worth war is much worse.
There is no instance of a nation benefiting from prolonged warfare
I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.
Never ascribe to malice that which can adequately be explained by incompetence.
It is only the dead who have seen the end of war
All the forces in the world are not so powerful as an idea whose time has come.
War is just when it is necessary; arms are permissible when there is no hope except in arms.
There was never a bad peace or a good war.
The end move in politics is always to pick up a gun.
There is no avoiding war; it can only be postponed to the advantage of others.
Heaven cannot brook two suns, nor earth two masters.
Either war is obsolete, or men are.
