Statement by the Acting Secretary of State (Welles), July 24, 1941
It will be recalled that in 1940 the Japanese Government gave expression on several occasions to its desire that conditions of disturbance should not spread to the region of the Pacific, with special references to the Netherlands East Indies and French Indochina. This desire was expressly concurred in by many other governments, including the Government of the United States. In statements by this Government, it was made clear that any alteration in the existing status of such areas by other than peaceful processes could not but be prejudicial to the security and peace of the entire Pacific area and that this conclusion was based on a doctrine which has universal application.
On September 23, 1940, referring to the events then rapidly happening in the Indochina situation, the Secretary of State stated that it seemed obvious that the existing situation was being upset and that the changes were being achieved under duress. Present developments relating to Indochina provide clear indication that further changes are now being effected under duress.
The present unfortunate situation in which the French Government of Vichy and the French Government of Indochina find themselves is, of course, well known. It is only too clear that they are in no position to resist the pressure exercised upon them.
There is no doubt as to the attitude of the Government and people of the United States toward acts of aggression carried out by use or threat of armed force. That attitude has been made abundantly clear.
By the course which it has followed and is following in regard to Indochina, the Japanese Government is giving clear indication that it is determined to pursue an objective of expansion by force or threat of force.
There is not apparent to the Government of the United States any valid ground upon which the Japanese Government would be warranted in occupying Indochina or establishing bases in that area as measures of self‑defense.
There is not the slightest ground for belief on the part of even the most credulous that the Governments of the United States, of Great Britain, or of the Netherlands have any territorial ambitions in Indochina or have been planning any moves which could have been regarded as threats to Japan. This Government can, therefore, only conclude
that the action of Japan is undertaken because of the estimated value to Japan of bases in that region primarily for purposes of further and more obvious movements of conquest in adjacent areas.
In the light of previous developments, steps such as are now being taken by the Government of Japan endanger the peaceful use by peaceful nations of the Pacific. They tend to jeopardize the procurement by the United States of essential materials such as tin and rubber which are necessary for the normal economy of this country and the consummation of our defense program. The purchase of tin, rubber, oil, or other raw materials in the Pacific area on equal terms with other nations requiring these materials has never been denied to Japan. The steps which the Japanese Government has taken also endanger the safety of other areas of the Pacific, including the Philippine Islands.
The Government and people of this country fully realize that such developments bear directly upon the vital problem of our national security.
