Seoul’s End-of-War Initiative Splits US-Japan-ROK Coordination on North Korea Policy

Full prediction
Over seven days, South Korea’s push to formally end the Korean War will sharpen policy divergences with Washington and Tokyo over sequencing peace, sanctions relief, and force posture. While public messaging will stress unity, internal debates will intensify around US troop levels, extended deterrence guarantees, and conditions for a peace treaty. Markets will start to price in a small but non-zero probability of future US force reductions, affecting long-term defense planning and regional hedging strategies. Confirmation would be leaks or public statements showing different emphases among the three capitals; denial would require rapid trilateral consensus on a common approach.
