President Trump Says He’ll Stop Joint Military Exercises With South Korea. Here’s Why U.S. Troops Are There in the First Place

President Donald Trump made history on Tuesday when he became the first U.S. President to meet with a North Korean dictator for denuclearization talks. But, though his meeting on Singapore's Sentosa Island was with North Korean leader Kim Jong Un, South Korea also played a large part in what happened.

As TIME has reported, the U.S. made perhaps the most significant concession at the summit by agreeing to stop joint military exercises with South Korea.
