This was the state of affairs when the delegates to the Peace Conference began to assemble at Paris.
The Italian statesmen realized that these new conditions might raise serious questions as to certain territorial cessions which would come to Italy under the terms of the Pact of London, because their strategic necessity had disappeared with the dissolution of Austria-Hungary.

While they had every reason to assume that Great Britain and France would live up to their agreement, it was hardly to be expected that under the changed conditions and in the circumstances attending the negotiation and signature of the Pact, the British and French statesmen would be disposed to protest against modifications of the proposed boundary if the United States and other nations, not parties to the agreement, should insist upon changes as a matter of justice to the new state of the Serbs, Croats, and Slovenes.

It apparently was considered expedient, by the Italian representatives, in view of the situation which had developed, to increase rather than to reduce their claims along the Dalmatian coast in order that they might have something which could be surrendered in a compromise without giving up the boundaries laid down in the Pact of London.
It is probable, too, that these additional claims were advanced by Italy in order to offset in a measure the claims of the Jugo-Slavs, who through the Serbian delegates at Paris were making territorial demands which the Italians declared to be extravagant and which, if granted, would materially reduce the proposed cessions to Italy under the Pact of London.

Furthermore, the Italian Government appeared to be by no means pleased with the idea of a Jugo-Slav state so strong that it might become a commercial, if not a naval, rival of Italy in the Adriatic.

The Italian delegates in private interviews showed great bitterness toward the Slavs, who, they declared, had, as Austrian subjects, waged war against Italy and taken part in the cruel and wanton acts attendant upon the invasion of the northern Italian provinces.
