If you can strike in a way that prevents retaliation that would, by definition, not be mutually assured destruction.
Correct, which is in part why so much effort went into developing credible second strike capabilities, building up all parts of the nuclear triad, and closing the supposed missile gap. Because both the US and USSR had sufficiently credible second strike capabilities, it made a first strike much less strategically attractive and reduced the likelihood of one occurring. I’m not sure how your comment disagrees with mine? I see them as two sides of the same coin.
