The third reason is of a most general character. One psychological defense mechanism against danger is to forget about it. This attitude is as common as it is disastrous. It may turn a limited danger into a fatal difficulty. The last and most important reason is that the world has become thoroughly interdependent and the time has come for the positive use of this interdependence.
International cooperation is obviously difficult.
It lacks any tradi- tion. It is best started by modest activities that are obviously in everyone's interest. War-prevention by defense seems to be a good candidate for such cooperation. This would be particularly true if the effort would be both modest and effective. This book is an excellent example of an international initiative that with a minimal effort could have a maximal beneficial effect.
