Trump can be really obnoxious. This however, seems to me to be just an example of Trump being Trump, and not in a bad way this time.
He reminds me of Jesse Ventura in that regard, just talking in a regular way, off the cuff and completely unrehearsed, and not really caring what people think. Politicians who refuse to speak Polticalese, carrying on and on and on with the express purpose of not saying anything at all, are refreshing. Man, to listen to politician after politician say nothing is so boring, and then to hear the fifth estate analyse the speech in order to critique the politician for actually slipping up and saying something has made following politics absolutely pointless.
So, he noticed she was of Korean descent? Well, a lot of people make a big deal that Trump is white, and guess what?

Men tend to notice if women are pretty or not, and women notice things about men too. That is just who we are as people. There is nothing particularly wrong with that. Calling women ugly to their face like Trump has done defines his obnoxiousness. Calling someone pretty is considered way too informal, and sure it is, but it is not an insult or disrespect in any way.
For years people how useful it is for Americans to have access to people of different backgrounds who can speak the Arab or whatever, to be able to get an inside track on what is going on in the world.
Trump suggesting that this is a woman who might be able to negotiate with NKorea is not all that far fetched or out of the ordinary for what experts have been suggesting all along.
