The Russians' Preemptive Pre-Proofing Against Penetration

The Russians have often proven themselves to be pretty bad at imaginative pre-proofing against penetration. I think there will be a lot of counterintelligence officers in Moscow scouring through these documents to get some sense of where their primary vulnerabilities lie. The other countries which are now having reasons to be angry or embarrassed and clearly Ukraine given the amount of information leaking. There's also a certain degree of satisfaction the Ukrainians have not been particularly forthcoming with their Western allies indeed their Western backers.
