4. It seems to us improbable that Bulgaria would, at any rate before Turkey's entry into the war, invite the Germans to send forces into Bulgaria. Bulgaria is already aware that the facilities that she has accorded to Germany have earned her great resentment in Russia and it is improbable that she would wish to give Russia any further cause for complaint. It is also improbable that the Germans would be willing to spare substantial forces for Bulgaria until they were convinced that the imminence of Turkey's entry into the war made this essential.
