This was on February 8th. By the 9th, they had to sign the treaty. This could not be delayed, not only on account of Leopold's birthday, but for a more important reason, which Kuehlmann undoubtedly explained to Czernin: "If we should send our representatives into the Ukraine just now, they might really convince themselves that the Rada does not exist; and then we shall have to face a single All-Russian delegation which would spoil our prospects in the negotiations."... By the Austro-Hungarian delegation we were advised to put principle aside and to place the question on a more practical plane. Then the German delegation would be disposed to concessions.... It was unthinkable that the Germans should decide to continue the war over, say, the Moon Islands, if you put this demand in concrete form. We replied that we were ready to look into such concessions as their German colleagues were prepared to make. "So far we have been contending for the self-determination of the Lithuanians, Poles, Livonians, Letts, Esthonians, and other peoples; and on all these issues you have told us that such self-determination is out of the question. Now let us see what your plans are in regard to the self-determination of another people--the Russians; what designs and plans of a military strategic nature are behind your seizure of the Moon Islands. For these islands, as an integral part of an independent Esthonian Republic, or as a possession of the Federated Russian Republic would have only a defensive military importance, while in the hands of Germany they would assume offensive significance, menacing the most vital centers of our country, and especially Petrograd."
