So the USA is offering a huge bounty on a North Korean entity as he is the mastermind of a attack on critical US infrastructure. But I'm not sure if there will be takers here, as we all know that North Korean are very close knit and I doubt that somehow, someone will be a turn coat unless they really wanted to get out of the country and set up a live outside and most likely in the US but it's a big risk on them.
