And I hedged that. Anything short of 100% responsibility with humans is a failure. I get investigating how it occurred, but that needs be very careful to separate ought from is.
The obvious questions is when the intelligence needed to be updated (ie, when Iran decided to put a girls school on a military base) and when Iran made that fact public, or at least when the US intel should have figured it out with satellites and other sources.
If it's years old then definitely on human. Intelligence will always be flaky in these hostile countries.
