UN has always had one or more questionable staff members for a very long time.
I'm not surprised that eventually idiots got more power than they should have had and it all came crashing down but it's a terrible shame that the server had to pay for PWA and global staff mistakes.
As for the removal of all staff, it's entirely possible that he was ordered to do it, but it wouldn't surprise me either if it was something he decided himself.
Normal everyday staff are always caught in the crossfire of management mistakes.
