Trump is chasing a fall meeting with North Korea's Kim Jong-un while relations with South Korea sour — bad news for the US-Korea alliance and for anyone worried about the growing US debt pile.

• A Kim meeting is being pushed for as soon as this fall, possibly squeezed in around a November China trip.
• South Koreans are reacting badly, with public calls to cut ties with Washington and build their own nuclear deterrent.
• The timing is awkward: the US Army buys mobile artillery from Korea's Hanwha, and LG is in talks to supply drone batteries.
• US debt is set to hit $40 trillion months earlier than expected, partly from tariff revenue that got struck down.
• Lenders are demanding higher rates, and with more debt issued short-term, interest costs reset faster and a debt spiral becomes a real risk.

Outlook: Expect more strain with Seoul and higher borrowing costs, with a Trump-Kim meeting still uncertain and Canada tariffs paused rather than resolved.
