I think it might go more like:
Putin will demand the evidence about the "Russians" and will potentially allow their extradition (because he knows already that the server isn't available for evidence)
Mueller won't send the evidence. He can't prove who did what to ANYTHING.
Putin won't allow extradition and will demand the accusations be withdrawn in lieu of no evidence.
DOJ now has a potential case of fraud against Mueller, who now is liable for a defamation suit.
Why? If this was traceable, it would have been discovered in a week into the investigation. In fact, there is nothing discoverable that couldn't have been found in the first month.
raid Mueller's offices and confiscate all materials
to be inspected by the IG's office
or other designated team
