You’ve probably seen the memes. The eccentric jumpsuits, the high-waisted pants, and those very specific haircuts that launch a thousand internet jokes. But honestly, when we talk about Kim Jong Il and Kim Jong Un, we usually spend way too much time on the caricature and not enough on the actual mechanics of how they've kept that country running for over thirty years.
It’s easy to dismiss them as "crazy" or "unpredictable." In reality, they have been ruthlessly rational.
Most people think Kim Jong Un just stepped into his father’s shoes and kept the status quo. That’s not quite right. While they share the same bloodline—the "Paektu Bloodline"—their styles of ruling are worlds apart. One was a shadow dweller who barely spoke in public; the other is a media-savvy millennial who brings his daughter to missile launches.
The Shadow vs. The Spotlight
Kim Jong Il was, by all accounts, an enigma. He ruled from 1994 until his death in late 2011. During those 17 years, the world barely ever heard his voice. He was the "Dear Leader," a man who preferred the dark of a cinema or the privacy of an armored train. He was obsessed with film—literally kidnapping a South Korean director, Shin Sang-ok, to make a North Korean version of Godzilla.
He didn't do public speeches. He didn't do "meet and greets."
Then you have Kim Jong Un.

When he took over at roughly 27 years old, everyone expected a puppet. They thought the old generals would eat him alive. Instead, he purged the old guard—sometimes quite literally—and started mimicking his grandfather, Kim Il Sung. He speaks to crowds. He smiles for the cameras. He hugs soldiers. It’s a complete 180 from his father’s reclusive vibe.
A Tale of Two Successions
One major difference is the prep time. Kim Jong Il had decades. He was officially designated as the heir back in the 70s and spent twenty years learning the ropes of the Workers' Party of Korea (WPK) before his father died in 1994. He was a master of the bureaucracy.
Kim Jong Un? He had about three years.
His older brother, Kim Jong Nam, was famously caught trying to go to Tokyo Disneyland on a fake passport in 2001, which basically ended his chances at the throne. That left the "young general." Because his transition was so rushed, he had to be way more aggressive to prove he was the boss.
Military First or Economy First?
If you want to understand the shift in North Korea, you have to look at their slogans.

Under Kim Jong Il, it was all about Songun—Military First. Basically, if there was a single bag of rice left, it went to a soldier. This was largely a survival tactic because the 1990s were a disaster for the country. Between the collapse of the Soviet Union and horrific floods, North Korea hit a famine known as the "Arduous March." Estimates vary, but hundreds of thousands of people died.
Kim Jong Il’s response was to double down on the army to prevent a coup or a collapse.
Kim Jong Un shifted the goalposts. He introduced the Byungjin policy. This was the idea of developing nuclear weapons and the economy simultaneously. He’s much more of a pragmatist than his father was. He realized that the "Military First" logic was starving the country to death, so he allowed small-scale private markets (called jangmadang) to flourish.
Today, in 2026, the North Korean economy is a weird hybrid. It’s still a command economy, but there’s a generation of "market kids" who have grown up buying and selling smuggled goods from China.
The Nuclear Obsession
Both men saw nukes as the ultimate insurance policy. They watched what happened to Gaddafi in Libya and Saddam Hussein in Iraq. Their takeaway? If you don't have the big bomb, the Americans will eventually come for you.

- Kim Jong Il: Conducted two nuclear tests (2006 and 2009). He used the nuclear program as a bargaining chip to get food aid and sanctions relief.
- Kim Jong Un: Has conducted four tests himself and launched dozens of missiles. He isn't interested in trading the nukes for food. He wants the world to accept North Korea as a permanent nuclear power.
He’s much more "audacious," a word his father reportedly used to describe him. He doesn't just want to survive; he wants to be taken seriously on the global stage. That’s why he met with Donald Trump in Singapore and Hanoi. His father would have never dreamed of that kind of public spectacle.
The "Jangmadang" Generation Problem
The biggest challenge facing Kim Jong Un right now isn't the US military—it's his own people's changing tastes.
People born after the famine don't remember the "glory days" of state rations. They don't feel like they owe the Kim family their lives because the government didn't feed them—the markets did. This has forced Kim Jong Un to be much more modern in his propaganda.
He uses his wife, Ri Sol Ju, to project an image of a "normal" first family. More recently, the constant presence of his daughter, Kim Ju Ae, at high-level events suggests he’s already thinking about the fourth generation of the Paektu bloodline.
Misconceptions You Should Probably Drop
- They are "Crazy": They aren't. Every provocation—every missile launch on a US holiday—is calculated. It’s about leverage and internal messaging.
- The Country is a Frozen Time Capsule: It’s not. Pyongyang has high-rises, smartphones (highly monitored, obviously), and even a domestic version of Netflix.
- The Military is One Solid Block: There are deep internal factions. Kim Jong Un spends a lot of time moving generals around so no one gets too comfortable.
What's Next?
If you’re trying to keep track of where this is going, stop looking at the missile counts for a second and look at the internal culture.
The real tension in North Korea isn't between the North and South anymore—it's between the Kim family’s total control and the creeping influence of outside information. Whether it’s K-dramas on USB sticks or the "market generation" wanting more consumer goods, the pressure is building from the inside out.
What you can do now:
Keep an eye on the official North Korean state media (KCNA) for mentions of Kim Ju Ae’s "titles." If she starts getting referred to with the same "Great" or "Supreme" adjectives used for her father, the succession is officially in high gear. Also, watch the trade figures with China; that’s the real lifeline that determines if Kim Jong Un can keep his "economy and nukes" balancing act going through 2026 and beyond.
