None of that really matters. In the military you don't give classified data even to your mother unless she has a clearance. So, either the dude is being used by the military intelligence (assuming such a thing even exists in this series) or he's going to spend the next 20 years of his career in a prison, or he knew what he was doing and gave compromised information. Or the Gundam 00 script writers ate something quite different instead of their Matsutake.

Frankly, if I had to choose between compromised data or Sumeragi being brainless, I'd choose the former option. Although even that doesn't mean she would be redeemed, as it'd be hardly professional to base a whole operation on intelligence received from a dubious source...
