North Korea proves they're up to the task however!
Look at the ages of the North Korean women involved.
There are reasons why, with some important exceptions, American female television reporters and anchors are likely to have their on-camera careers end at a fairly young age unless they are lucky enough to keep a youthful appearance. By contrast, Asian media and viewers continue to place a priority on maturity and experience, which means older Asian women may continue to get selected for on-air coverage of important events. That's not just true in North Korea but throughout Asian media.
I'm married so I am not going to get into discussing the relative attractiveness of specific women. Also, beauty is obviously in the eye of the beholder. However, as a general rule, I think it's pretty clear that Korean women often meet Western standards of attractiveness, and Korean women often age better than their Western sisters.
I don't think going beyond that generic statement would serve a valid purpose — we're on a conservative discussion site, not a “rate her hotness” site — so while physical attractiveness is a legitimate job requirement of broadcast media and one I don't mind discussing, it's not a subject I want to discuss in detail about specific women in media.
