Star Trek was telling stories of the Cold War in space.

And many other stories in space entirely unrelated to the cold war. There really aren't that many TOS episodes that have Klingons in them.

Klingons... and in TNG, at some points the role was taken over by the Romulans. TNG's "The Drumhead" is essentially about McCarthy's hearings.

I still like it.
