President Donald Trump directed the Pentagon to scale back joint military exercises with South Korea as the annual drills were getting underway, citing Seoul's refusal to join the U.S. war against Iran and his relationship with North Korean leader Kim Jong Un.

David Silbey, a Cornell University professor of history specializing in military history, defense policy, and battlefield analysis, says the decision reflects broader trends in Trump's foreign policy and U.S. military posture.
Silbey says:
“President Trump’s scaling down of exercises with South Korea reflects a few consistent themes in his foreign policy. First is his continuing fascination with dictators, whether it’s Putin, Xi, or Kim Jong Un. Trump loves a strongman and has continually made decisions based off of that fixation.
“Second is the military overstretch it reflects. Because of the war with Iran, U.S. forces (especially naval) have been stretched to the brink, as we’ve seen with the deteriorating conditions aboard the USS Abraham Lincoln. The Navy has been forced to pull resources out of the Pacific region and send them to the Middle East. Reducing the commitment to the South Korean exercises probably reflects a reduction that was inevitable anyway.”
“Finally, is the continuing neglect of American allies. It’s not just about South Korea — Taiwan, Japan, and the Philippines are watching as well. So is China.”
