The US has reliable information that ex-President of Azerbaijan Heydar Aliyev is the one, who disrupted the signing of a peace accord between Armenia and Azerbaijan in 1999, Zerkalo Baku newspaper writes referring to a highly informed western diplomat. According to the source, a "pro-Armenian" agreement was arranged at the time, and at the insistence of the US Heydar Aliyev not only had to agree, but also partially assume the mission of persuading Armenian leader Robert Kocharian to give up pro-Russian orientation in exchange for inclusion of the country in a union with Azerbaijan in the sphere of US interests. I.e. Armenia had the opportunity to participate in all regional oil and gas projects. As noted by the source, Aliyev succeeded in fulfilling his task. At the same time, in the words of the anonymous American diplomat, official Baku at the time deliberately organized a leakage of information for the Kremlin "on the betrayal of Robert Kocharian." Russian special services did the rest, the source noted, reminding that exactly at that time the well-known act of terrorism was committed in the Armenian Parliament. The diplomat explains in his own way the reasons, which induced Heydar Aliyev to act in the fashion he did. In his opinion, not only the peace accord ready to being signed did not meet the interests of Azerbaijan, it was also unfavorable for H. Aliyev as a politician. In case the peace accord was signed, Aliyev would have remained in the history of Azerbaijan as a President, "who ceded Karabakh to Armenia," and he could not admit it, of course, Zerkalo writes.
