The only explanation you can find for this type of lunacy is money.
In case you haven't been following the story, Dennis Rodman has convinced a bunch of basketball players to go to North Korea with him so that the Kim Jong-Un regime can have a crop of confused, ignorant useful idiots to use as propaganda. CNN's Chris Cuomo had a shouting match with Rodman that produced nothing informative.
The body language of the other players speaks for itself--they have no idea what's going on and they are seeing dollar signs instead of the real ramifications of playing exhibition basketball in one of the most hated and repressive countries in the world. They thought they could go overseas, play a few pickup games, and get paid (I absolutely refuse to believe that any of them are there solely on their own dime--someone is paying someone here).
North Korea slaughters and starves its own people. Millions have lived their entire lives in the shadow of horror and fear. And Dennis Rodman and his friends are enabling the third generation dictator of a homicidal regime. Whatever he's on--drugs, alcohol, hubris--it isn't enough to make up for the fact that he's being used by a clown.
