Funny, but in cold Russia we do not make mass-movies, and mass-stories about the British…
Ilya Vaiser

Cultural point about the UK. When we are being sarcastic, we sometimes leave out words in relation to what other people are claiming. So the proper version is:

“[The UK establishment claim that] ISIS and even Russia are barbarians, but [they hypocritically insist, by contrast, that] dodgy UK politicos merely make the proverbial time-honored ‘honest mistakes.’”

That’s really what I meant. Sorry for the ambiguity.
