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. This world in
arms is not spending money alone. It is spending
the sweat of its laborers, the genius of its
scientists, the hopes of its children. This is not
a way of life at all in any true sense. Under the
clouds of war, it is humanity hanging on a cross
of iron.
- Dwight Eisenhower

When the tyrant has disposed of foreign enemies by conquest or treaty,
and there is nothing more to fear from them, then he is always stirring up
some war or other, in order that the people may require a leader.
- Plato

You can no more win a war than you can win an
earthquake.
- Jeannette Rankin

WAR! - Huuuh - What is it good for? Absolutely
nothing.
- Edwin Starr

Give me the money that has been spent in war and I will clothe every man, woman, and child in an attire of which kings and queens will be proud. I will build a schoolhouse in every valley over the whole earth. I will crown every hillside with a place of worship consecrated to peace. ~Charles Sumner

It'll be a great day when education gets all the money it wants and the Air Force has to hold a bake sale to buy bombers

Mankind must put an end to war, or war will put an end to mankind. ~John F. Kennedy, 1961

A great war leaves the country with three armies - an army of cripples, an army of mourners, and an army of thieves. ~German Proverb
