Trump and Kim Jong Un: What Happened to the 'Love Letters'?

The Summits That Changed Nothing

Between 2018 and 2019, Donald Trump and Kim Jong Un held three summits — in Singapore, Hanoi, and Panmunjom — exchanged what Trump called "beautiful letters," and generated extraordinary media coverage and Nobel Peace Prize speculation. It was historic, theatrical, and ultimately consequential in ways opposite to what was promised.

North Korea did not denuclearize. It did not stop testing. It used the diplomatic engagement to gain international legitimacy and to buy time while expanding its nuclear arsenal. By virtually every technical measure, North Korea emerged from the Trump-Kim dialogue era with more nuclear capability, not less.

Where North Korea's Program Is Now

North Korea's nuclear and missile programs have continued advancing through Biden's term and into Trump's second. Current assessments suggest:

• 30-50 nuclear warheads, with production capacity to build more annually
• Intercontinental ballistic missiles capable of reaching the continental United States
• Submarine-launched ballistic missile development underway
• Tactical nuclear weapons for battlefield use against South Korean and Japanese targets
• Advanced missile technology cooperation with Russia — North Korean ammunition and personnel have been deployed in Ukraine

The denuclearization window, if it ever existed, has effectively closed. The question is no longer how to get North Korea to give up its weapons. It is how to deter their use.

Why Personal Diplomacy Failed

The failure of the Trump-Kim dialogue illuminates a broader lesson about summitry as a substitute for strategy. North Korea had clear, consistent strategic logic: nuclear weapons are the only guarantee of regime survival (Saddam Hussein and Muammar Gaddafi gave them up; both were removed from power). No inducement the US can credibly offer would outweigh that calculation.

Trump's approach treated the relationship as a personality problem — as if charm and rapport with Kim could overcome 70 years of strategic logic. The Hanoi summit collapsed because North Korea demanded removal of all sanctions in exchange for dismantling a single nuclear facility. This was not a negotiating position that evidenced any real intent to denuclearize.

What Options Remain

There are no good options on North Korea. The realistic range runs from:

Deterrence and containment: Accept North Korea as a nuclear state, focus on preventing use and proliferation, maintain alliance commitments to South Korea and Japan.

Conditional engagement: Use diplomatic contact to manage tensions and pursue limited agreements on testing moratoriums, while not expecting full denuclearization.

Regime change: Not a serious policy option given North Korea's conventional military capabilities, nuclear deterrent, and Chinese protection.

The first option is increasingly the de facto policy of every administration, even if none will formally articulate it.

FAQ

How many nuclear weapons does North Korea have? Estimates vary, but most analysts believe North Korea has between 40 and 60 nuclear warheads as of 2026, with the capacity to produce several more annually.

Can North Korea's missiles reach the US? Yes. North Korea has successfully tested ICBMs with the range to reach the continental United States. Whether the missiles have reliable guidance systems and heat shields to survive reentry is debated.

Why does China protect North Korea? China views North Korean collapse as creating unacceptable risks: a refugee crisis, a unified Korea allied with the US on China's border, and general instability. North Korea, as uncomfortable as it is, is preferable to China compared to these alternatives.
