WHAT THE EXERCISES ARE

This year’s exercises began on April 1 and are expected to continue through the end of the month, possibly longer. But as a reminder of the underlying tensions, training to evacuate Americans from South Korea during a contingency was also held this month, though not formally part of the Foal Eagle program. The South Korean military will instead focus on providing "stable support" for the talks between President Moon Jae-in and North Korean leader Kim Jong Un to be held at the border village of Panmunjom, according to the Joint Chiefs of Staff. Moon told reporters in December that he urged Washington to put the war games off until after South Korea’s Pyeongchang Winter Olympics and Paralympics, which wrapped up in March.
South Korea and the United States suspend their Foal Eagle millitary exercises. Furthermore, they also finish parts of the Key Resolve exercises.
