The shaping of the Sevres Treaty with the U.S. President W.Wilson’s border arbitrary award revealed the U.S. unwillingness to put Armenians in ward, since it was unsufficiently profitable. American Senators warned diplomats of the Republic of Armenia that the Treaty would urge the wide-front Turkish offensive. All procrastinations of Washington in negotiations did not help the official Erevan to compete the Kemalists neither in the sphere of formation and operation of the armed forces, nor in politics. This failure resulted in the heavy defeat, suffered in the Turkish-Armenian war of 1920 and led to the official repudiation of the Sevres Treaty; it was arranged on November 26-27 of the same year in Alexandropol. At the same time, the Sevres Treaty contained a lot of engineering soslutions, usable for a settlement of the Armenian Question.
