Americans own Defense Intelligence Agency’s leaked classified report contradicts this report and suggests Iran has only been set back by a few months.
They were saying on NPR this morning that DIA doesn't incorporate all sources (eg: no HUMINT/SIGINT from CIA/NSA).
It might be where based on things like satellite photos they cannot draw certain conclusions that are unable to be discussed publicly due to blowing a source.
The GP said two things: "leaked" and "classified". For that reason, I strongly suspect that "unable to be discussed publicly due to blowing a source" is the reason for anything... unless you think it was "leaked" as a deliberate misdirection.
As I said in my previous statement, the journalist said that they made their assessment using only things like satellite data and that folks like NSA/CIA might have a different take but it would not be discussed in public due to the nature of HUMINT.
So imagine someone leaks a report that doesn't use all available sources to bolster their side of a story or because they lack the theory of mind to understand it's not the bombshell they think it is.
I don't know how to write this out more simply for you.
