Freedom Edge 2023: South Korea Champions US and Japan in Groundbreaking Joint Air and Naval Exercises

North Korea has sharply criticized the recent trilateral military exercises as a ‘reckless display of military might.’

On September 15, 2025, the United States, South Korea, and Japan initiated joint air and naval exercises, dubbed “Freedom Edge,” which have been denounced by North Korea as a “dangerous strategy.”

These maneuvers, launched off the coast of South Korea’s Jeju Island, will continue until Friday, showcasing advanced ballistic missile capabilities and air defense simulations.

The US Indo-Pacific Command highlighted that these drills represent the “most sophisticated demonstration of trilateral defense collaboration to date.”

According to the South Korean Defence Ministry, the exercises are aimed at bolstering the allies’ capacity to face escalating nuclear and missile threats posed by North Korea, as reported by The Associated Press.

Protests erupted in Seoul on Monday in opposition to the military operations.

In remarks released by North Korean state media, Kim Jong Un’s influential sister, Kim Yo Jong, criticized the joint effort by South Korea, Japan, and the US as a “reckless show of strength” in “inappropriate locations.”

She warned that these military drills would “certainly result in adverse consequences for the parties involved.”

Just last week, Kim Jong Un inspected military research facilities in Pyongyang, announcing an acceleration of both conventional army and nuclear development.

The North Korean mission to the United Nations reiterated on Monday that the nation’s status as a nuclear power is irreversible.

Pyongyang has repeatedly shown disinterest in restarting nuclear negotiations with Seoul and Washington following a breakdown of talks during Donald Trump’s presidency.

Moreover, North Korea has strengthened its ties with Moscow in recent years, recently dispatching troops to the Russian region of Kursk amidst conflicts related to Ukraine’s territorial gains in August 2024.

Simultaneously, the nation maintains robust connections with China, its largest trading partner. Earlier this month, Kim met with Chinese President Xi Jinping and Russian President Vladimir Putin at a significant military parade in China.

During his visit to Beijing, Kim assured Xi that their bilateral friendship “will remain steadfast.”
