Most "facts" about North Korea are jokes from the south that the west takes way too fucking seriously. So basically every crazy thing you hear about North Korea is a bullet to anyone who is too dense to look into anything. The title that makes the first Kim the immortal leader is a ceremonial title, they don't tell them he invented the hamburger or he's never shit. All you have to do is look at Aljazera or any other media source that doesn't hold a western bias towards the world. It's all ridiculous.
Kim Jong-un (Chosŏn'gŭl: 김정은; Korean pronunciation: [kim.dʑʌŋ.ɯn] or [kim] [tɕʌŋ.ɯn]; born 8 January 1982–84 or 5 July 1984) is the Chairman of the Workers' Party of Korea (WPK) and supreme leader of the Democratic People's Republic of Korea (DPRK), commonly referred to as North Korea. Kim is the second child of Kim Jong-il (1941–2011) and Ko Yong-hui. Before taking power, Kim was rarely seen in public, and many of the activities of Kim and his government remain unknown. Even details such as what year he was born, and whether he did indeed attend a Western school under a pseudonym, are difficult to confirm.
Kim was declared the supreme leader following the state funeral of his father on 28 December 2011. Kim holds the titles of Chairman of the Workers' Party of Korea, Chairman of the Central Military Commission, Chairman of the State Affairs Commission, Supreme Commander of the Korean People's Army, and presidium member of the Politburo Standing Committee of the Workers' Party of Korea. Kim was promoted to the rank of Marshal of North Korea in the Korean People's Army on 18 July 2012, consolidating his position as the Supreme Commander of the Armed Forces and is often referred to as Marshal Kim Jong-un or "the Marshal" by state media. Kim obtained two degrees, one in physics at Kim Il-sung University, and another as an Army officer at the Kim Il-sung Military University.
On 12 December 2013 official North Korean news outlets released reports that due to alleged "treachery," he had ordered the execution of his uncle Jang Song-thaek. On 9 March 2014, Kim Jong-un was elected unopposed to the Supreme People's Assembly. He is the first North Korean leader to have been born after the country's founding. Kim Jong-un is widely believed to have ordered the assassination of his brother, Kim Jong-nam in Malaysia in February 2017.

Curiosity is the single most important attribute with which humans are born. More than a simple desire to discover or know things, curiosity is a powerful tool, like a scalpel or a searchlight. Curiosity changes us. It is also a way to effect change, perhaps even on a global level.
