South Korea in August 2026: the most important developments in security
South Korea's security picture in August 2026 was shaped by the annual joint exercise with the United States. On August 10, the two countries announced it would run from August 17 to 27, with combined field training and computer-simulated command post exercises. On August 17, US President Donald Trump ordered the Pentagon to scale back the exercises, and Trump described North Korean leader Kim Jong Un as a "good friend". On August 19, the drills were cut short, and the South Korean foreign ministry said Washington had not notified Seoul in advance. The exercises ended ahead of schedule on August 21. North Korea said this was a response to its criticism.
North Korea carried out several missile launches. It fired a ballistic missile on August 12, its second in a week, ahead of the exercise. On August 20, it fired about a dozen short-range ballistic missiles into the sea, hours after Trump said he planned to meet Kim this year. The missiles fell outside Japan's exclusive economic zone, and no damage was reported. A further suspected ballistic missile followed on August 21, and the US military said the firings pose no immediate threat to the US or its allies. On August 12, Pyongyang vowed an "unsurvivable" retaliatory capability over South Korea's nuclear submarine push. South Korea estimated that North Korea has up to 120 nuclear warheads, against Trump's figure of 57.
North Korea's role in the war in Ukraine drew attention. On August 11, Ukraine said Russia had attacked with North Korean ballistic missiles, killing nine people across the country. On August 17, Ukraine said Russia would replace border troops with North Korean soldiers to free up manpower.
Seoul also advanced its own defence programmes. It moved forward on a next-generation ship-launched missile and on its nuclear submarine programme, began an upgrade of the K2 main battle tank, and received US approval for a potential sale of AIM-9X air-to-air missiles. On August 5, police raided the headquarters of Starbucks Korea in a criminal investigation into its "Tank Day" promotion, examined as a potential criminal insult.
