Wow, that's a lot of accusations! :)
> They clearly dropped the ball after a few early successes in the space race.
Not true - even in 90's when designing ISS Russian experience with space stations was one of the reasons to invite them to the project.
> By the 70s the Soviet program was in tatters and a joke
Presumably while continuing space stations program with ever increasing capabilities and flight times? Or have you heard about VEGA interplanetary automatic project - admittedly in 80's?
> by the 80s the Shuttle did incredible things that the capsule based approach simple couldn't do (repairing hubble, etc)
Have you heard about reviving Salyut-7 using Soyuz spacecraft? Dzhanibekov-Savinykh flight?
> Obviously, the cost estimates of the shuttle were lower than real cost, but I can't think of any major project where that wasn't true.
But Shuttle was particularly bad miss by costs, wasn't it?
> the Shuttle was retired for a capsule based approach that is a private and public partnership
I'd agree - but note how many years NASA pays to Roscosmos for flying astronauts to ISS and back. Shuttle was retired rather for safety reasons.
> between NASA and companies like SpaceX who are showing us how cheap rockets can be
Which also might be an attempt to reach Russian low cost figures by other means?
> Its unfair to compare failed test projects, which were also fairly uninspired copies, like the Buran and the N1 to workhorses like the Saturn V and the Shuttle.
Here you're clearly missing the mark. N1 wasn't a copy of anything whatsoever. All-kerosene 5-stages stack? Record (bigger than Saturn-5) liftoff thrust? Number of separate engines? Spherical tanks? Not that Buran was particularly uninspired - for one, Energia was capable of flying even without Buran, for another, Buran used kerosine-LOX as main orbital fuel - with advantages both in efficiency and toxicity over Shuttle.
> The Russiophilia around here is pretty high and unfairly so.
You might be right here - it's highly subjective - but you have to admit USSR had plenty of original achievements.
> oddball projects like mounting 50 cal guns on space stations
If you'd analyze carefully, you'll see that those were mostly perfect rational decisions given information which was available at the time. Sense of oddity can be explained by incomplete review.
> pathetic attempts at cloning western successes like the Concorde
That one I don't get at all. How Tu-144, which flew before Concorde, be a copy of Concorde?
