Star Trek

Are the Romulans, Cardassians, and Klingons really that dense? Also I noticed that every enemy race the federation encounters seems soo similar. Black hair, grey uniform, short tempered, greedy, and unintelligent. I always looked at the the war in Deep Space nine was somthing on par with world war two. Gemery:Cardassia, Bajorans:Jews, Klingons:Russia, Romulans:China (either could be interchangable) and the Dominion would more on par with Japan.

However...I see really little deviation from the nature of all of these  people as I said...the only variences seemed to boil down to differnt forhead doodads and different starship colors or shapes. 

I don't think any of them were 2 dimensional. I never saw them face off against the mooninites. Wait a minute, there were those creatures in "The Loss".

Ya beat me to it - that's the show where Troi lost her abilities to read people.
