That's what I pretty much intend to think.
Kim's son at such a young age wouldn't know and do as much as his father's thoughts and needs.
Kim Jong Il had three sons (and a daughter, but she is irrelevant to succession). The first son was groomed to replace him, but they fell out. The second son, I think, is gay, so he is out. The third son is who we have.
Reports are that Kim Jong Un is JUST like his father except worse. His father's primary concern was controlling locally, but he has been trained to want world control.
Time will tell if he can handle it, but we traded one mad man for a madder man.
