In the phor main Trek series, metaphor is used phor everything (did you see what I did there?) Even the more popular alien races. Who can deny the Ferenghi are Jews? Hell, most of them are played by Jewish actors.
And the Klingons HAVE to be Japanese Shogun Warriors (despite being somewhat BIGGER, of course).
This is not news to Trekkies/Trekkers.
But have they ever considered the Vulcans might be Swedes? Cold, logical and humourless. They’re SWEDES – I’m TELLING you!
Beam me up, Scotty!
