……Chalabi’s interlocutors in the US government were a fairly small and well-known group, stacked heavily toward the top of the totem pole and very much on the appointive, civilian side — start with the acronyms OSD and OVP.

If one of those guys gets pegged for giving Chalabi info that later ended up in the hands of Iranian intelligence, everything up till now will seem like it was a breeze.
