History doesn't necessarily repeat, but it rhymes.
Just because the Chernobyl and fall of the USSR theme was the inspiration of Trek VI doesn't mean things like that don't keep happening throughout the span of time. Look at the hubris that led to Fukushima, for instance, or the arab spring parallel to the fall of the USSR. It could be that what you see today with Syria and Iran holding onto outdated dictatorial models and a certain swath of america sympathetic to burning Korans is just another flavor of the end of the soviet union and the old-guard that became to attached to the unending conflict.
A far better example of "dating" Trek would be The Way to Eden, which was a far too literal take on hippie culture.
