In my personal opinion there is absolutely no way that "five eyes" nations should allow ex-intelligence-agency personnel, particularly from the NSA and related SIGINT entities (CSE, GCHQ, etc) to go work in the private sector for non democratic regimes.

You want to go work for Denmark, or Germany? Sure, get the appropriate permit from the department of state. For the UAE, or Iran, or Myanmar? No. I don't care if the royal family running the UAE are supposedly our friends.

Any person that is a citizen of a five eyes + partner nation, which goes to work for a project like this, should immediately find themselves the target of their country-of-citizenship's intelligence agencies.
