The DNC dismissal of the VIPS narrative is wholly misleading and mostly fabricated.
The Intel agencies have not “concluded” anything. They have “assessed” with varying levels of confidence, what they believe happened to the DNC servers. Moreover, their “assessment” was made without the benefit of actually being able to examine the servers and any of the forensic evidence directly, instead having had to rely on the reports prepared by Crowdstrike, a “cyber attribution” firm specialised in identifying Russian hacking.
It should be noted that of the three agencies who did “assess” the DNC data loss, the CIA and FBI assessed with “high confidence” but the NSA — the agency in which these dissenting analysts used to serve — assessed only with “moderate confidence.”
Also, the narrative put forth in The Nation has the added advantage of conforming with what WikiLeaks and Assange have maintained all along, namely that it was a leak, not a hack. Indeed, WikiLeaks confidant and ex-Ambassador from the UK Craig Murray, who became famous himself for whistleblowing on CIA torture and rendition programs, has said all along that he actually met the leaker, and that s/he was a disgruntled DNC insider.
