In his speech he describes how President Reagan won the trust of the Soviet leadership in order to bring to an end the Cold War and its risk of nuclear armageddon. http://www.larouchepub.com/eiw/public/2015/2015_1-9/2015-08/pdf/10-14_4208.pdf

Reagan's meeting with Gorbachev did not rely on position papers written by staff. It relied on a hand-written memo by Reagan himself that stressed respect for the Soviet leadership and a clear realization that negotiation must not expect the Soviet leaders to do something that is not in the true interest of their country. The way to end the conflict, Reagan wrote, is to cooperate toward a common goal. Matlock said that Reagan refused to personalize disagreements or to speak derogatorily of any Soviet leader.

Matlock makes the point that Reagan's successors have done a thorough job of destroying this trust. In the last two years the destruction of trust has been total.
