Donald Trump described Kim Jong Un as 'a friend of mine' during remarks in Washington on Tuesday, responding to a reporter's question about why North Korea can possess nuclear weapons while the US wages war to prevent Iran from acquiring them. Trump's answer was entirely relational: 'He likes Trump, doesn't like a lot of other people. I'm about the only person in the entire world that he likes, and I like him.' The framing is notable for what it omits. South Korea's Defence Minister Ahn Gyu-back stated last week that North Korea possesses between 80 and 120 nuclear warheads — a figure significantly higher than Trump's own recent assertion of 57. Trump acknowledged the arsenal is 'pretty large' but waved it off with 'not like us' and 'as long as I'm around, he's going to be fine. You know why? Because he respects me and he likes me.' Trump blamed previous administrations for North Korea's nuclear status — 'you had a different president, and they could have stopped him' — while offering no mechanism for how his personal relationship with Kim translates into denuclearization or even restraint. The two held summits in 2018 and 2019, but diplomacy collapsed over US demands that Pyongyang give up its weapons. Since then, Kim has expanded his missile arsenal and deepened alignments with Russia over Ukraine and with China. The Iran comparison sharpens the contradiction. Trump abandoned the 2015 Iran nuclear agreement during his first term in 2018, then launched a war alongside Israel on February 28 of this year, stating Iran could not have a nuclear weapon. Iran has denied seeking one, pointing to the 2015 deal it signed with world powers that curbed its programme in exchange for sanctions relief. The US-Israel war on Iran has disrupted global energy supplies, raised fuel costs, and eroded Trump's approval ahead of the November midterm elections. The asymmetry is structural, not incidental. North Korea already has the weapons; Iran does not. Trump's response to the first is personal affection; his response to the second is military force. The variable is not nonproliferation principle — it is the bilateral relationship and the political utility of each posture. Trump said he planned to hold in-person talks with Kim before year's end, but North Korea has not formally committed to any such meeting. Kim's diplomatic position has strengthened considerably since 2019: a tighter relationship with Moscow provides economic and military cover, while China offers strategic depth. There is no indication Pyongyang sees any urgency in re-engaging. The net effect is a US nonproliferation posture that is entirely personality-dependent, with no institutional framework, no treaty structure, and no articulated doctrine. One nuclear-armed state gets friendship; another gets war. The distinguishing principle is whether the leader 'likes Trump.'
