They would essentially be the same discussion, like you said, so I don't think it would matter that much.
I would probably at least mention and define Khrushchev's 'Peaceful Coexistence' policy - then use that to lead into all the thaw/not thaw stuff.
But I'd bring in the arms race too (like how that lead to summits like Geneva and how it carried on despite peaceful coexistence), probably not a huge paragraph dedicated to it though <- then that would be answering it for either interpretation.
