It is pretty clear that the South Korean left really dislikes John Bolton now that they resulted to racist name calling which probably means he is doing a good job protecting America’s interests:

Former Unification Minister Jeong Se-hyun claimed Tuesday that the abrupt ending of the summit in Hanoi between U.S. President Donald trump and North Korean leader Kim Jong-un was “intentional” and engineered by National Security Adviser John Bolton.

Calling Bolton a “big hurdle” with regard to issues related to the Korean Peninsula, Jeong alleged the security adviser persuaded Trump to walk away from the talks with Kim. 

“Bolton, a North Korea hawk, reminds me of a white cavalry leader in an old Western movie who doesn’t feel guilty about killing Native Americans,” Jeong said while meeting with lawmakers of the ruling Democratic Party of Korea (DPK). “I believe the breakdown was intentionally brought about by the U.S. side, and Bolton was the villain in this.”
