149 Mr John Curtin, Prime Minister, to Mr Winston Churchill, U.K. Prime Minister
Cablegram Johcu 5 CANBERRA, [2 December 1941] 
MOST SECRET AND PERSONAL
I have your telegram WINCH No. 7  and am grateful to you for sending it for our guidance.
I most cordially concur in your action in addressing the President  in the terms you have used. Your suggestion is in accord with the views expressed at the War Cabinet yesterday.  However, I make this further suggestion. In our view if we are to effectively deter Japan from an aggressive move, a greater concentration of naval strength (not necessarily all British) is desirable. I believe that Japan's obstinacy is grounded in the belief that America would, at the best, be slow to come in and that from many (corrupt group ? causes) a time lag in American shooting would be inevitable.
If in addition the President could be got to the point of giving effect to your strong personal appeal this would be a complete deterrent to Japan's entry into the war.
