This was a horrifying possibility. Baran began to ask: Was there some other way to send a counter-strike signal? There was a sense of life-saving preciousness in such a setting about connectivity itself. To hold it, manage it, protect and control it - in the face of the extreme pressures of a nuclear balance, such connection marked the difference between safety and catastrophe. 2.
