The early 1970s were a time of
détente between the
Eastern Bloc and
NATO nations.
SALT I, the
Anti-Ballistic Missile Treaty, the
Helsinki Accords, and other international agreements were negotiated during this time. According to Shevchenko's memoirs, he became increasingly disillusioned with real Soviet attitudes toward these international agreements. He had immediate access to the inner workings of the Soviet foreign policy establishment and felt that the Soviet government was cheating on the intent of the agreements for short-term political gain, which would be ultimately to its own disadvantage. He also stated clearly that Soviet leaders, while pretending to respect the UN, actually disdained it and viewed it solely as a means to advance Soviet interests covertly or otherwise. Furthermore, Moscow's requirement for him, as a UN officer, to put Soviet interests ahead of UN interests but to pretend otherwise was a violation of the
UN Charter. He also came to believe that the Soviets' internal economic policies and their insistence on hard-line communist centralization of power were depriving the
Russian people of their freedom and ability to better themselves and their country. His long years of exposure to Western democracies convinced him that the Soviets were "taking the wrong path" economically and politically. He also was tired of and bitter about not being free and not being able to speak freely, and he wanted personal freedom. He briefly considered resigning his position with the UN and returning to the Soviet Union in an attempt to change the system from within, but he soon came to the realization that it would have been an impossible task, as he had neither the power nor the influence to effect any significant change. He did not like that option because he felt that such a life in retirement would be meaningless. By 1975, he had decided to defect. He made contact with the CIA to seek
political asylum. However, the CIA pressured him to continue at his UN post and to supply them with inside information on Soviet political plans. Although fearful of the consequences if he were to be found out by the
KGB, he reluctantly agreed with the idea that if he wanted to fight against the regime's existence, that was an opportunity to do so in a way with real effect or power. For the next three years, he became in effect a "triple agent". Outwardly, a dedicated servant of the United Nations but covertly promoting Soviet political aims and secretly reporting the Soviets' hidden political agenda to the CIA. In early 1978, he became aware of increased KGB surveillance of his movements. Suddenly, on March 31, 1978, he received a cable from
Moscow that summoned him to return to the Soviet Union for "consultations". Suspicious of the demand and realizing that if he flew to Moscow, he might never be permitted to return to his UN duties or even to leave the Soviet Union, he called his CIA contact and demanded for it to fulfill their promise of political asylum. ==Defection==
