Kim Jong-un's two older brothers were considered "black sheep" of the family. Kim Jong-nam likely fell out of favor when caught in a plot to visit Tokyo Disneyland in 2001, though Kim Jong-nam himself stated that he was not favored due to advocating for reform in the government. He had a reputation as a troublemaker within the family, and publicly stated in 2011 that North Korea should transition out of his family's dynasty. On 14 February 2017, Kim Jong-nam was assassinated with the chemical nerve agent VX at Kuala Lumpur International Airport in Malaysia. Two women, an Indonesian and a Vietnamese, smeared the agent on Kim Jong-nam's face; both women were released after it was determined that they had been tricked by North Korean operatives, who had told them that the act was a prank for a Japanese comedy program and that the substance was lotion. Four North Koreans fled Malaysia on the day of the murder. Kim Jong-nam was survived by his wife and two children. His son, Kim Han-sol, has also criticized the regime. In an interview with Finnish media in 2012, Kim Han-sol openly criticized the reclusive regime and the government saying that he has always dreamed that one day he would return to his homeland to "make things better". Ever since the death of his father, his whereabouts have been unknown.
