**Deck**: South Korean President Lee Jae‑myung says North Korea’s isolation is so extreme that all communication lines are cut and Pyongyang now labels Seoul ‘the most hostile state in the world.’ In detailed comments on his talks with Donald Trump, Lee warned that if Kim Jong Un amasses more nuclear material than he thinks he needs to survive, the temptation to sell it abroad will grow—and Trump agreed.

On the Korean Peninsula, the silence is starting to sound more dangerous than the missile launches. South Korean President Lee Jae‑myung has offered a stark description of relations with Pyongyang, saying that every line of communication has been severed and that North Korea now describes the South as “the most hostile state in the world.” In this framing, the two Koreas are no longer a divided nation inching toward reconciliation, but “two hostile states” with no working hotlines—even in an emergency.

Lee’s comments, delivered in an extended account of his recent interactions with Donald Trump, capture a strategic landscape where personal ties among leaders sit uneasily atop structural risks from North Korea’s advancing nuclear program. According to Lee, Trump recently posted—and then personally cited—a photo of himself walking with Kim Jong Un, telling the South Korean president that it was time to focus on the North Korea issue again. Lee recounted Trump describing himself as a “peacemaker,” to which Lee replied that while the United States plays the central role in security and regime survival questions, Seoul sees itself as the “pacemaker” that must create conditions for dialogue.

Behind the rhetoric lies a blunt warning. Lee said he told Trump that if North Korea accumulates nuclear material beyond what Kim believes is necessary for regime survival, “the temptation to export that material could grow,” creating what Lee called a very serious danger. Trump, by Lee’s account, agreed with that assessment. The scenario is not theoretical: a cash‑strapped, heavily sanctioned regime with a history of missile and military technology sales could, if it has surplus fissile material or warhead know‑how, look abroad for customers.

The human stakes stretch far beyond the peninsula. Any export of nuclear materials or technology by North Korea would immediately raise proliferation fears in the Middle East, South Asia or among non‑state actors. For populations in far‑off cities, the risk is that a geopolitical stalemate in Northeast Asia turns into a radiological or nuclear threat somewhere else. For ordinary South Koreans, the more immediate impact is psychological: living under a neighbor that not only rejects dialogue but could one day treat its arsenal as an export commodity.

Lee’s account also sheds light on Trump’s thinking. He described the former US president as eager, even frustrated, to revive talks with Kim but uncertain how to proceed, reportedly asking Lee, “What is the solution?” Trump has lamented that stronger action was not taken before North Korea fully acquired nuclear weapons, while acknowledging—after Lee’s prompting—that the current reality demands a different approach from past non‑nuclear states. At the same time, Trump floated the idea of South Korea rapidly building ten American naval vessels, a request Lee said he met with assurances that Seoul would do its best.

Strategically, Lee’s message is that the architecture of deterrence and diplomacy built over decades is eroding. Without even emergency hotlines, the risk of miscalculation—say, over a limited clash at sea or an artillery incident—rises sharply. If Washington and Pyongyang do return to talks centered on the US–North Korea channel, as Lee suggests they must, Seoul faces the challenge of remaining relevant to decisions that directly affect its security.

The picture Lee paints is of a triangle in which Washington holds the key to talks, Pyongyang holds the nuclear weapons, and Seoul holds much of the conventional vulnerability. That imbalance makes the question of North Korean nuclear exports more than a theoretical academic concern; it is a measure of how far the regime might go if it feels both secure enough in its arsenal and desperate enough for hard currency.

The next signals to watch include whether North Korea responds publicly to Lee’s characterization of relations, any changes in its nuclear rhetoric or activity detected by monitoring agencies, signs of US efforts to quietly re‑establish contact with Pyongyang, and whether South Korea takes concrete steps—diplomatic, military or industrial—to position itself as the “pacemaker” Lee says it wants to be in the next round of peninsula diplomacy.
