I don't deny that some American soldiers may have recognised the beauty of Vietnamese women, but surely you understand that the nature of their interactions was not a matter of beauty.
A lot of the Vietnamese women that slept with American soldiers were directed into doing so by the North Vietnamese army and the Vietcong in order to collect Intel.
This is in no way comparable to the image that black rappers and entertainers send out into the world.
Ah, men... such fallible creatures. You build a whole military industrial complex around them, don them in the best equipment, train them, give them salaries and careers and they piss away good intel for some paid for coochie. Send the whole lot back to the production line, I say.
