Really, WashPost?

Karen DeYoung, Washington Post, two days ago:

[Nikki Haley] said the United States had no plans to decrease its military exercises with North Korea, despite calls from China and Russia to do so, in exchange for gradual deescalation of its prohibited weapons activities.

On-line version was quietly though belatedly edited and now reads

She said the United States had no plans to decrease its military exercises with South Korea, despite calls from China and Russia to do so. 

The correction has not reached the various newspappers who trustingly syndicate WashPost stories. The two words have the same number of letters so it is an easy mistake to make.
