Answer: South Korea, US and Japan
Notes: South Korea, the US, and Japan launched their inaugural trilateral multi-domain exercise, Freedom Edge, on South Korea’s Jeju Island. The three-day exercise aims to enhance security cooperation amid North Korea's strengthened ties with Russia. Activities include ballistic missile defense, air defense, antisubmarine warfare, search and rescue, maritime interdiction, and defensive cyber training. This follows a recent summit where North Korea and Russia signed a strategic partnership treaty, including military support clauses.
