I lived there for a while. I found them to be some of the most courteous people I’ve ever met. They don’t suffer fools though, and sometimes Americans do some really dumb stuff abroad...
Regards,
My nephew lives there now with his Korean wife. He says Americans don’t walk on water any more but, except for certain fools, are highly respected. Nephew probably won’t come back here except for family visits. His attitude toward the norks current threats and bluster is, “Bring it on, it’s time we take care of old business.”
