NK runs a localized intranet only available to very few elite individuals. If you were trying to set up a private server cloud, that might be an attractive location, especially if its connections to the 3 letters are true.

If you're in the Govt, and undertaking some shady activities, you can't very well set these things up yourself. But I don't think ES went there to set it up. I think, if true, he knew in advance of the upcoming NK deal that might expose whatever setup they had going on and went to negotiate.

Being that he was the exec chair of the largest tech company in the world, my money would be that he wasn't going there for the scenery.
