Wikileaks is nothing but Russian government's propaganda at this point. It has discredited itself.
I would say that it is in the US government's interest to discredit wikileaks, as their leaks tend to air dirty American laundry. But a lack of similarly embarrassing leaks about Russia dies not Russian propaganda make. It could simply be that Russian whistleblowers are more likely to meet with a fatal exposure to polonium.
Please don't conduct political ragewars here. They're tedious and not in the spirit of intellectual curiosity which is supposed to guide this site.
If you can find the will to do so, the very best thing is to be charitable. In this case that might mean remembering that the commenter has likely only heard one heavily politicized side of the story, and has been conditioned by such one-sided information to reflexively associate one thing with another. Then you might respond in a way that confounds their expectation in a positive, surprising manner, instead of getting angry and defensive, which can only reinforce it.
Admittedly that's hard to do and never something one must do. But it is likely the most effective thing to do. When one person responds from a conditioned reflex but another has the presence not to do so, that's how things get unstuck.
The demographics of HN are so unevenly distributed that it's impossible for the discourse here to be objective about many topics, but we can and do at least control for basic respect, and if you watch closely you'll notice that we care about that, and act on it, a lot.
