War is a bloody, killing business. You’ve got to spill their blood, or they will spill yours! Rip them up the belly. Shoot them in the guts. When shells are hitting all around you and you wipe the dirt off your face and realize that instead of dirt it’s the blood and guts of what was once your best friend beside you, you’ll know what to do.

From General George Patton’s speech to the United States Third Army, 1944

One cannot fight a war with one hand tied behind one’s back.

Winston Churchill

War does not determine who is right, only who is left.

Attributed to Bertrand Russell

Mankind must put an end to war – or war will put an end to mankind.

John F. Kennedy, address before the United Nations, 1961

I hate war as only a soldier who has lived it can, only as one who has seen its brutality, its futility, its stupidity.

Dwight D. Eisenhower, address before the Canadian Club, 1946

You may not be interested in war, but war is interested in you.
