5. In order to attain the overall objective, first priority in the provision of forces and resources of the United States and Great Britain, including reorientation from the European Theater to the Pacific and Far East, will be given to meeting requirements of tasks necessary to the execution of the over-all strategic concept and to the basic undertakings fundamental to the prosecution of the war.
[Page 1311]The invasion of Japan and operations directly connected therewith are the supreme operations in the war against Japan; forces and resources will be allocated on the required scale to assure that invasion can be accomplished at the earliest practicable date. No other operations will be undertaken which hazard the success of, or delay, these main operations.

7. The inclusion under Basic Undertakings of terms concerning a specific resource such as cargo shipping is undesirable.

It is agreeable, however, to include in the text of the report the following paragraph:—

cargo shipping

Present estimates of the requirements for cargo shipping indicate the position to be sufficiently manageable to provide for the maximum effort in the prosecution of the war against Japan, for the maintenance of the war-making capacity of the British Commonwealth of Nations and the Western Hemisphere, in so far as it is connected with the prosecution of the war against Japan, and for an additional amount for civilian requirements. Should a substantial conflict arise, the shipping situation will be a matter for examination by the two governments at the time and in the light of changed conditions.
