Preventive war was an invention of Hitler. I would not even listen to anyone seriously that came and talked about such a thing. - Dwight D. Eisenhower

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. The cost of one modern heavy bomber is this: a modern brick school in more than 30 cities. It is two electric power plants, each serving a town of 60,000 population. It is two fine, fully equipped hospitals. It is some fifty miles of concrete pavement. We pay for a single fighter plane with a half million bushels of wheat. We pay for a single destroyer with new homes that could have housed more than 8,000 people. This is, I repeat, the best way of life to be found on the road the world has been taking. This is not a way of life at all, in any true sense. Under the cloud of threatening war, it is humanity hanging from a cross of iron. ... Is there no other way the world may live?

You have broader considerations that might follow what you would call the falling domino principle. You have a row of dominoes set up. You knock over the first one, and what will happen to the last one is the certainty that it will go over very quickly. So you could have the beginning of a disintegration that would have the most profound influences.

Freedom under law is like the air we breathe.
