John Sipher has an excellent explanatory post up, “Is Trump a Russian Agent?: Explaining Terms of Art and Examining the Facts.”
As I’ve been coming to believe, Sipher feels that Trump is more a useful idiot than a fellow traveler. (Sorry for the obsolete terminology; I’ve read too much old spy stuff.)
But he things it’s possible that one or another of Trump’s associates may be actively working with the Russians. Paul Manafort is a shoo-in, and Carter Page a definite possibility. I still would like to know exactly how Page got to be one of Trump’s early “foreign policy advisors.” He was really nobody, and his writings were cray-cray. But, in the useful idiot department, more than one of Trump’s crime cartel were happy to have Russian help, never bothered to report the contacts to the FBI, and lied about them. (And yes, I know about Sam Clovis and a few other people connected to Page, but unless you have a step by step connection from Page to all those folks, I’ve probably read it.)
Sipher also feels that the counterintelligence part of the Mueller investigation is unlikely to come to light. I think Adam may have said as much. I think that is the probable outcome, but I also think that a good way to foil continuing interference from the Russians would be to get as much out as possible. We’re doing information warfare here, and the best way to blunt the opponent’s offensive is to tell everyone what it is. That has to be balanced against revealing sources and methods, of course, but I think that concern has gone too far in the direction of secrecy.
Ultimately Trump must be brought to account, whether through impeachment or in the 2020 election.
