No, no, no, you've got it all wrong. In the 1950s, it became clear to the US that we couldn't defeat the USSR itself in a war. It was suicidal with the rise of nuclear weapons. So we decided the only way to defeat them was via an "inside job". We searched for suitable candidates and selected Gorbachev. We cultivated him for decades, helped his rise to power in 1985, then he collapsed the USSR for us.
The USSR came to a similar realization in the 1960s. The only way to defeat the USA was through an inside job. They found a suitable candidate, carefully cultivated him, paired him with another agent, and helped them in their rise to power. This operation was so secret that not even our own mole, Gorbachev, knew about it. Unfortunately for the Soviets, their agents were seven years too late.
