That's not if he's competent or not. More than a few presidents are racist by modern standards, I would have to look at the details about Vietnam but there was no good option there. They got the troops out but sold an ally down the river to do it. Nixon didn't start the ear, probably thought he could win it cut and run but in hindsight o don't think any one else would have done any better. I suppose cutting and running earlier may have been a better idea.
