I said "South Korea took North Korean POWs, without NK’s consent or knowledge."
You asked "Did they now?" and "Why would they do that?" I don't know why you asked "Did they now?" to Did SK take NK's soldiers? (This is what this article is about, you said you read the article). Maybe when you ask "why would they do that?" you were referring to when I said "Now NK can demand that SK return the soldiers."
Anyways have a good night get some sleep
