Despite warnings that they could completely derail recent progress toward diplomacy and peace, the Pentagon announced on Monday that planned U.S.-South Korea military exercises on the Korean Peninsula will proceed in April.

The Pentagon’s announcement comes in stark contrast to North Korea’s promise earlier this month to halt all missile tests as diplomatic talks—including a possible in-person meeting between U.S. President Donald Trump and Kim Jong-un—continue to gain momentum.

“The annual springtime drills between the United States and South Korea include two specific exercises: Foal Eagle and Key Resolve,” the Washington Post reported on Monday. “The latter is a command-and-control exercise that uses a significant amount of computer simulation and involves about 12,200 U.S. troops and 10,000 South Koreans, Logan said. Foal Eagle includes actual field maneuvers, with about 11,500 U.S. troops and 290,000 South Koreans participating.”

Though the U.S. portrays its joint military drills with South Korea as “defense-oriented,” North Korea has denounced the exercises as simulations of “all-out war.”
