THE LIMITATIONS OF NATO SIR,—It would be fruitless to continue

this corre- spondence—even if your editorial indulgence is not now exhausted—for a reason which although little understood by the majority of the people is at the heart of the defence controversy. Very briefly the supporters of our present policy have not realised (from my point of view) that the application of nuclear energy for military purposes has made it necessary to reassess the age-old and hitherto correct assumption that physical force must be the basis of defence strategy in a world of power-politics..To un- derstand and to draw the correct conclusions from the fact that physical force in nuclear form is useless is what 1 call breaking through the thought barrier in defence thinking. It must have been very difficult for many people—intelligent people—some hundreds of years ago to believe that the earth was not flat.— Yours faithfully.
