Erode trust in our government/ intelligence agencies? Really? You mean the ones that lie and obfuscate to us repeatedly, spy  on us, ignore the majorities wishes repeatedly, etc. etc.? The same government that has a near all time low level of trust ALREADY?

Anything the Russians could possibly do, would be akin to dancing on rubble. 

And of course you conveniently omit the usually sucessful efforts of our government to destabilize, undermine and overthrow so many other governments over the years(both overtly and covertly), but whine oh so pitifully when it appears that maybe, perhaps it was done to us. The renowned American hypocrisy on full display. Laughable if not so sad.  But you carry on with your undying trust in our government and it's 17(!) intelligence agencies and it's well advertised quest for full-spectrum domination of the planet.
