When the 1936 Olympics were held, Nazi Germany could do all it could to act civilized but all of the pictures of a happy audience around a smiling Hitler could not erase the fact that the nation was in the grip of a thuggish regime that threw opponents into prison and terrorized Jews. [Large-scale slaughter would occur later.]
It is interesting to watch the reactions to the North Korean delegation's appearance at this year's Olympics. The savages of the world don't always seem to be savages. [Herman Goering is said to have had a certain charm.]
We would so like the truly evil people of the world to be open to reformation but reality tells another story. The North Korean dictatorship is mind-boggling in its cruelties. The cruel can also be sly.
