"It is, of course, also in our interest that Japan wants to secure for herself further possessions in the South, Indo-China, etc., just as every measure of Japan directed toward expansion is in principle welcomed by us. I shall give you detailed instructions within the near future, relative to the consequences which might, and no doubt will, result from the occupation of Iceland by American military forces, and the attitude which we will take toward Japan in this connection. As a directive for talks we can advise you already today that the sending of American military forces to the support of England into a territory which has been officially announced by us as combat area, shows not only Roosevelt’s aggressive intentions, but the fact of the intrusion of American military forces into the combat area in support of England is in itself an aggression against Germany and Europe. After all, one cannot enter a theater of war in which two armies are fighting, and join the army of one side without the intention of shooting and without actually doing so. I do not doubt for a moment that in case of the outbreak of hostilities between Germany and America, in which case today already it may be considered as an absolutely established fact that only America will be the aggressor, Japan will fulfill her obligations, as agreed upon in the Three-Power Pact. However, I ask you to employ all available means in further insisting upon Japan’s entry into the war against Russia at the soonest possible date, as I have mentioned already in my note to Matsuoka. The sooner this entry is effected, the better. The natural objective still remains that we and Japan join hands on the Trans-Siberian railroad, before winter starts. After the collapse of Russia, however, the position of the Three-Power Pact states in the world will be so gigantic, that the question of England's collapse or the total destruction of the English islands will only be a matter of time. An America totally isolated from the rest of the world would then be faced with our taking possession of the remaining positions of the British Empire which are important for the Three-Power-Pact countries. I have the unshakeable conviction that a carrying through of the new order as desired by us will be a matter of course, and there will be no insurmountable difficulties if the countries of the Three-Power Pact stand close together and encounter every action of the Americans with the same weapons."
