The United States and South Korea decided to call off their joint exercise “Foal Eagle” and “Key Resolve” and instead bifurcate them into smaller exercises. This is being done to ease tensions with North Korea. “Key Resolve” will be replaced by “Dongmaeng” which is also known as alliance in English, Foal Eagle drills will be replaced by a smaller battalion-sized exercise.
This decision has been made after there was a failure to reach an agreement on denuclearisation during the summit in Hanoi, Vietnam between President Donald Trump and North Korean leader Kim Jong Un.
