SEOUL, South Korea (AP) — The United States and South Korea will begin their biggest combined military training in years next week in the face of an increasingly aggressive North Korea. The North has been ramping up weapons tests and threats of nuclear conflict with Seoul and Washington. South Korea’s military says the drills underscore Washington and Seoul’s commitment to restore large-scale training. The two countries canceled some of their regular drills and downsized others to computer simulations in recent years to create space for diplomacy with North Korea and because of COVID-19 concerns. The drills will almost surely draw an angry reaction from North Korea, which describes all allied training as invasion rehearsals.
