I say this every Olympics, but if the South Africans were banned from the Olympics because of their Apartheid policies than why is North Korea with its far worse human rights violations allowed in the Olympics much less championed like President Moon is currently doing?:

President Moon Jae-in renewed calls for warmer ties with Pyongyang in his remarks at the World Taekwondo Championships in Muju County, North Jeolla on Saturday, inviting North Korea to participate in the PyeongChang Winter Olympics next year to “fulfill the Olympic spirit of harmony and promote world peace.”

Moon’s latest outreach to Pyongyang came as a 36-member demonstration team from the International Taekwondo Federation (ITF), which included 32 North Korean nationals, touched down at Gimpo International Airport last Friday to participate in the World Taekwondo’s (formerly World Taekwondo Federation) World Taekwondo Championships.

Among members of the delegation were Ri Yong-son, president of ITF, and Chang Ung, former ITF chief and the only North Korean member on the International Olympic Committee (IOC). While welcoming the North Korean taekwondo team, Moon said he was “delighted” to have accomplished the first “inter-Korean sports cooperation” in his administration, adding that he hopes the ITF and World Taekwondo help bring peace to the Korean Peninsula.  [Joong Ang Ilbo]

You can read more at the link, but a ban on North Korea competing in the Olympics seems like something President Trump could get traction on if he wanted.  It would be very interesting to see which countries would defend North Korea participating that supported a ban on South Africa from 1964-1988. The ban was only removed when the Apartheid system was scheduled for removal.  Why can’t the same standard be applied to the Kim regime which has done things far worse than what Apartheid South Africa ever did?
