Were the soviets afraid of americans as much as americans were afraid of them?

No, the Soviet leaders weren't afraid that the US would attack, because they knew that US would never attack first.

In the 1970s they were more afraid of the war with China, because they knew that if it started out as a conventional war, the Soviets would quickly get overwhelmed by sheer numbers, and would have to resort to nuclear weapons to keep from loosing.
