By mid-1987 the Soviet Union announced that it would start withdrawing its forces. Sibghatullah Mojaddedi was selected as the head of the Interim Islamic State of Afghanistan, in an attempt to reassert its legitimacy against the Moscow-sponsored Kabul regime. Mojaddedi, as head of the Interim Afghan Government, met with then Vice President of the United States George H. W. Bush, achieving a critical diplomatic victory for the Afghan resistance. Defeat of the Kabul government was their solution for peace. This confidence, sharpened by their distrust of the United Nations, virtually guaranteed their refusal to accept a political compromise.
