[4] The best proof is to be found in the Venizelist _White Book_, No. 36,--an exhaustive memorandum by M. Streit on the probabilities of the War, dated 13/26 March, 1915. It is both striking and illuminating that, while in dealing with the attitude of Bulgaria, the author considers three alternatives: (1) Bulgaria in alliance with the Entente. (2) Bulgaria as neutral. (3) Bulgaria as an enemy of the Entente. In dealing with the attitude of Greece he does not for a single moment contemplate more than two alternatives: (1) Greece as an ally of the Entente. (2) Greece as neutral. Further, in the course of the argument which follows, M. Streit discusses a possible understanding between Greece on the one part and Rumania and Bulgaria on the other, with the object either of a common neutrality or, failing that, of a simultaneous entry into war in favour of the Entente, "on whose side alone we can range ourselves."
