This general trend, that echnology rather thanpolicy leads, carries vith it an intrinsic dan€ler. Technology by itsel-f is b1indto the dangers of the arms race; it l-eads to wherever the principles of science and engineering nay carry. In this situation it is inperative that statesmen and-politicai leaders acccpt thcir responsibility. If they do not, the arns race iscertain to go out of control-. )+9!.
