Trump Ordered Pentagon to Substantially Reduce Joint Military Drills With South Korea

The U.S. and South Korea have started their annual military drills. But President Donald Trump’s latest order changes how future exercises are carried out. On August 16, the Trump ordered Pentagon directive called for a major cut in joint exercises with South Korea. Trump pointed to the cost of the drills and Seoul’s refusal to join U.S. actions involving Iran. He also highlighted his relationship with North Korean leader Kim Jong Un.

What Changed?

• Ulchi Freedom Shield 2026 began on August 17. (Annual large-scale joint military exercise)
• The exercise is set to run through August 27.
• About 18,000 South Korean troops are taking part.
• The Pentagon has not said how future drills will be changed.

So far, the order has not stopped the current exercise. The focus is now on what happens after these drills end.

Trump has often argued that U.S. allies should take more responsibility for their own defense. About 28,500 U.S. troops are based in South Korea. Washington also wants Seoul to share more of the cost of the alliance. Trump also brought Iran into the dispute. He said he asked South Korea to join U.S. efforts to denuclearize Iran. Seoul declined. That shows the issue is part of wider differences between Washington and Seoul.

But the cost is not the only issue. Joint drills give U.S. and South Korean forces a chance to train together. They practice how to share information, respond to attacks, and work under pressure. Fewer drills save money. They also reduce the time available for joint training.

The US-South Korea joint military drills are not limited to live-fire training. They also use computer simulations and virtual exercises. These can cover missile attacks, cyber threats, and other combat situations.

This matters because North Korea’s military has also changed. North Korean forces have gained combat experience through their support for Russia in the war in Ukraine. U.S. and South Korean officials say that experience may help Pyongyang improve its battlefield skills. Trump’s comments also put his relationship with Kim back in focus.

Hours before the drills began, Trump said on Truth Social that he was “not happy” that the U.S. had agreed to take part. He also pointed to his “very good relationship” with Kim and said the exercises send a hostile message to North Korea.

Trump and Kim held three summits during Trump’s first term. Those meetings did not end North Korea’s nuclear or missile programs. Trump has continued to stress his personal relationship with Kim.

The reduction may give Washington more room to pursue talks with Pyongyang (capital of North Korea). But that is not yet a confirmed outcome. Analysts cited by Reuters have also said Trump could be trying to weaken North Korea’s growing ties with Russia.

Three signals to watch:

• Training: Will future drills become smaller or shorter?
• Diplomacy: Will Washington restart direct talks with Pyongyang?
• The alliance: Will South Korea be asked to carry more of the defense burden?

Ulchi Freedom Shield 2026 is still running as planned. The bigger test will come after August 27. If the next drills are much smaller, Trump’s order marks a wider change in U.S. policy. If there is little change, it may remain a limited move tied to costs and current disputes with Seoul.

Author’s note:

At the New York press release, we look beyond Trump’s decision to reduce U.S.-South Korea military drills and what it means for regional security. The next round of exercises will show whether this decision marks a lasting shift in U.S. policy toward South Korea and North Korea.
