Thursday’s drills, the first of the allies’ five rounds of firing exercises until mid-June, mark 70 years since the establishment of the military alliance between Seoul and Washington.
North Korea has typically reacted to such major South Korean-U.S. exercises with missile and other weapons tests.
Since the start of 2022, North Korea has test-launched more than 100 missiles but none since it fired a solid-fuel intercontinental ballistic missile in mid-April.
North Korea has argued its torrid pace of tests was meant to respond to the expanded military drills between the U.S. and South Korea, but observers say the North aims to advance its weapons development then wrest greater concessions from its rivals in eventual diplomacy.
