The closest thing i can find to a claim of fact in this link is:

one of my South Korean friends went to middle school in Australia, she witnessed how one of her classmates, the daughter of a North Korean diplomat, had to leave her little brother in North Korea while her father worked as a diplomat in Australia.

So just to be clear you are citing a story told to the author by anonymous someone who heard it as a child from another child.

Ordinary people in North Korea don’t even know that people in other countries can freely choose to study abroad when they want to. They don’t even know the expression “study abroad.”

lmao

This is garbage from a professional defector (left in 2005) with no ability for the reader to verify anything, published by a single-purpose anti-DPRK propaganda mill.

Do you have a more compelling citation?

Things like these make me wish the US didn’t ban its passport holders from even setting foot in the DPRK, some irony that is

The individual who wrote this article sounds horrible; at the bottom of his page it says he’s from North Korea himself. I can’t believe he sacrificed the lives of his family like that. If his family managed to escape with him, I wonder if they went after his extended family. Either way, I can’t believe he’d/they’d sacrifice their family; absolutely callous.

Definitely not the first time you’ve been wrong about the DPRK.
