One of his sons took over the North Korean regime after Kim Jong II passed away in December.

But now, another son is critical about the leadership of his brother.

According to a book excerpt published in the South Korean daily, Chosun IIbo, Kim Jong Nam says the North Korean regime won’t last long.

“The dynastic succession is a joke to the outside world… Without reforms, North Korea will collapse, and when such changes take place, the regime will collapse.”

The quotes appear in a Japanese book titled “My Father Kim Jong-Il and Me.”

The author Yoji Gomi exchanged emails and met three times in person with Kim Jong Nam over seven years.

So, why does the half brother make such gloomy predictions? A reporter for CNN explains...

“He thinks his brother has a lack of experience. He's too young. Also, he doesn't have enough time to be groomed.”

Known as a playboy, Kim Jong Nam spends must of his time in Macau. And he has reportedly never met his younger brother.

Although Jong Nam distrusts the leadership of his brother, the author of the book thinks he isn’t jealous. The author tells the Guardian...

“’I don't feel that he has any ambition to become leader of North Korea, but he wants to contribute to improving the situation in the country.’”

But Kim Jong Nam is not the only one questioning the new North Korean regime.

Former member of the U.S. National Security Council Victor Cha expressed similar concerns in the Christian Science Monitor saying...

“‘The efforts to put Kim Jong-un front and center immediately reflects a rushed succession process...”

The paper adds...

“Mr. Cha … predicts that what he calls ‘a Potemkin leadership transition’ in Pyongyang ‘will likely run into problems.’”

The book will hit the shelves in Japan on Wednesday.
