“Fundamentally, therefore: Conflict with Poland, beginning with an attack on Poland, will only be successful if the Western Powers keep out of it. If this is impossible, then it will be better to attack in the West and to settle Poland at the same time.
“The isolation of Poland is a matter of skillful politics.
“Japan is a weighty problem. Even if at first, for various reasons, her collaboration with us appears to be somewhat cool and restricted, it is nevertheless in Japan’s own interest to take the initiative in attacking Russia in good time.
“Economic relations with Russia are possible only if political relations have improved. A cautious trend is apparent in press comment. It is not impossible that Russia will show herself to be disinterested in the destruction of Poland. Should Russia take steps to oppose us, our relations with Japan may become closer.
“If there were an alliance of France, England, and Russia against Germany, Italy, and Japan, I would be constrained to attack England and France with a few annihilating blows. The Führer doubts the possibility of a peaceful settlement with England. We must prepare ourselves for the conflict. England sees in our development the foundation of a hegemony which would weaken England. England is therefore our enemy, and the conflict with England will be a life-and-death struggle.
“What will this struggle be like?”—Underscored in the German original.—
“England cannot deal with Germany and subjugate us with a few powerful blows. It is imperative for England that the war should be brought as near to the Ruhr Basin as possible. French blood will not be spared (West Wall). The possession of the Ruhr Basin will determine the duration of our resistance.
“The Dutch and Belgian air bases must be occupied by armed forces. Declarations of neutrality cannot be relied upon. If England and France intend the war between Germany and Poland to lead to a conflict, they will support Holland and Belgium in their neutrality and make them build fortifications in order finally to force them into cooperation.
“Albeit under protest, Belgium and Holland will yield to pressure.
“Therefore, if England intends to intervene in the Polish war, we must occupy Holland with lightning speed. We must aim at securing a new defense line on Dutch soil up to the Zuider Zee.
