I don't think comparisons between Kim and Hitler are fair. Kim is indeed a nutcase, but he's not invading other nations and, as far as I'm aware, is not killing millions of anyone, except possibly as a result of bad governance (ie starvation).

The idea he doesn't care about his people can be disputed, too, although it's shaky ground. One could argue that his reluctance to accept globalisation is basically an effort to protect his people from the sins of capitalism, however misguided that might be.

Do I believe this? No. But it's possible. We can only know what's going on there thanks to our media, who I trust about as much as I trust Kim himself.
