South Korea, the United States and Japan will conduct the Freedom Edge military exercise in September as tensions rise around North Korea's nuclear and missile programs. Seoul confirmed that the trilateral operation will proceed after Pyongyang threatened a forceful response to what it described as renewed American hostility.
The exercise will begin on September 7 and run for five days in waters off South Korea's southern Jeju Island. The three governments describe it as defensive and intended to strengthen their response to North Korean threats while supporting regional peace and stability.
Freedom Edge began in 2024 as a more integrated successor to earlier cooperation. It combines simultaneous air and naval activity to improve joint ballistic-missile defense, anti-submarine warfare, surveillance and other capabilities that require the three militaries to share information and operate together.
North Korea has denounced the drill as a reckless display of force and evidence of a confrontational strategy. Pyongyang also argues that the format serves a broader United States effort to encircle China and increase pressure on Russia, extending its criticism beyond the Korean Peninsula.
The decision follows an unsuccessful attempt by Donald Trump to create space for dialogue. The United States and South Korea ended their Ulchi Freedom Shield exercise six days earlier than planned after Trump ordered a substantial reduction, citing his relationship with Kim Jong Un and presenting the cut as a goodwill measure.
Pyongyang rejected that gesture, saying a shorter exercise did not change its provocative character. North Korea then launched about ten short-range ballistic missiles toward the sea and reiterated that talks with Washington cannot resume while denuclearization remains an American precondition.
North Korea's Foreign Ministry has also cited a possible United States sale of air-to-air missiles to South Korea among a series of hostile actions and promised a serious, immediate and powerful response. Since diplomacy collapsed in 2019, Kim has expanded his nuclear arsenal and strengthened ties with Russia, giving him greater leverage in any future negotiation.
Military coordination is also being affected by competing demands on American forces. A separate United States-South Korea amphibious drill may not take place in September after the Marine Corps cited operational constraints during the Middle East crisis, although it said participation levels were coordinated with Seoul and reaffirmed its commitment to the alliance.
