WASHINGTON (AP) — President Donald Trump has ordered the Pentagon to scale back annual joint military exercises with South Korea. He explained the decision by saying South Korea had declined to help with the “denuclearization” of Iran and he cited his good relationship with North Korea’s leader. Trump said in a social media post on Sunday that the exercises are costly and “send a signal that is totally inappropriate and hostile” to North Korea, which he said “has been unthreatening and respectful” during his time in the White House. The 11 days of exercises involving 18,000 South Korean soldiers began Monday and were designed to beef up readiness against North Korean threats.
