So nothing ‘coming out of’ the intelligence community has any value, but at the same time you have zero faith that in the case of certain sensitive matters, they are capable of keeping things to themselves if it aligns a certain way politically. Got it.
I think there’s an availability heuristic bias at play here. You’re forming assumptions based on the (IMO extremely limited) amount of information that does make it out from the security intelligence community, when it fact the overwhelming majority of what they do, involving matters of the highest degree of sensitivity and national importance, is kept properly protected and under wraps.
I have no opinion on whether what Kev has posted about is in fact true, but I don’t believe your assumption that such a thing could happen without us knowing about it holds water. My personal belief is that, in some cases, intelligence disasters can both happen AND be kept within tight circles of who knows. I’ll also add that there are probably periodic cases where something goes badly wrong, and the affected organization(s) can have a pretty good idea about what happened but will never be completely sure.
I would bet that the classified internal damage assessments of the Trump classified document holdings and potential information compromise is the sort of thing to make intelligence professionals shudder.
