The hydrogen bomb is not the answer to the Western peoples’ dream of full and final insurance of their security … While it has increased their striking power it has sharpened their anxiety and deepened their sense of insecurity.

With growing experience, all skillful commanders sought to profit by the power of the defensive, even when on the offensive.
