Annex "A" to I.D. 56. JAPANESE REACTIONS TO THE ABROGATION OF THE RUSSO-JAPANESE NEUTRALITY PACT 1. General Despite her defeat of Russia in the Russo-Japanese war, Japan never lost sight of the fact that Russia was the greatest potential menace to her from the strategical point of view. To this was added with the Russian Revolution the menace of Communism in which the Japanese saw the greatest danger to their whole political structure. The bogey of Bolshevism is probably at least as real to the Japanese as to the Central European States.
