I just think you overestimate the effectiveness of using the same tactics on Russia that they are using on us. They are effectively a dictatorship where voting results are a foregone conclusion. I think it would take a lot more espionage to undermine such a regime than it does to cause problems for a democracy. Do you think Putin would care if we leaked a document that said that in our opinion he was a megalomaniacal bully or revealed his sexual kinks (if any)?
I frankly hope our intelligence service is using their efforts on more useful and powerful ammunition.
