Yeah, I agree with the aspect of "at the time".
The issue seems to be, that even when the full technical results were known, much later, that they were suppressed.
Of course, anyone with any idea at all, of how a large bureaucracy works, knows that there still might not have been anyone at a high level who knew this.
How were they suppressed? The dispute about their purported uses and conflicting findings was very public and vocal. It was also three years ago. The Senate Select Committee on Intelligence (don't snicker) ripped into this and everything else CURVEBALL fed us. Only much later did we find out CURVEBALL was being managed by the Germans. We also found out through the SSCI that someone in the CIA noticed a rail line that CURVEBALL described would have had to run through a wall. Unfortunately, if you didn't toe the line at the CIA's WINPAC area, you were shunted off the project.
This in another example of the Intelligence Community telling the President something and him being transparent with us. Then, when it turns out to be wrong, or even if it doesn't, the media and other Dems accuse him of lying. I won't throw anyone to the winds just because the State Dept. assessed something one way while the Pentagon and CIA assessed it another. The State Dept. hasn't been shy about its agenda. Its entrenched bureaucrats think the Administration is supposed to execute their policies instead of vice versa.
