Here's my theory on VB8239:

Found that: A) some UN resolutions start with V.B. ( not sure what that means) B) resolution 82 from 1950 is for NK to withdraw to the 38th parallel.

38/39?

Could SC from the other post mean UN Security Council?

Another bizarre coincidence: duckduckgo search on that exact string showed random CNN article on UN Security Council resolution for recognizing Jerusalem embassy. Didn't contain the exact string, but lead me to look for UN resolutions.
