That was the point. GP said, "You can't hack a plant control system from outside because that network is physically isolated." What happened in Iran proves you can (or more strictly, that systems don't remain perfectly physically isolated even with an air gap).

Ah, I read that as "Iran didn't have an isolated system", in that they for some reason had a lapse of judgement.

Like a "See, the government even makes massive, obvious mistakes" type of comment.
