2017 in a nutshell right there.
The BS one hears today (against Russia, etc) are the "WMD"s of 2017.
There's a single superpower the last 2+ decades (Russia is no USSR) and it has a long history of pushing for its "interests" all over the world, starting wars, grabbing resources, overthrowing governments, supporting all kinds of lunatics and dictators.
And covering the whole damage they do with holier than though finger pointing, made up stories, and generally BS they serve a docile and mostly ignorant on anything happening outside their home state, much less worldwide, population. Or, actually, worse than ignorant: mostly informed from mainstream tv news presenting them the "enemy du jour", but with a complete lack of context and history, and with any nuance and details jumbled up in their minds (in a "Go to Austria, see the kangaroos" fashion).
Whether its a Joe Sixpack or a college educated person, in the majority of cases they equally lack context and perspective, and have no real reason to even try to get one, since they have no skin in the game: some other poor suckers will go and fight (e.g. literally poor whites, blacks and latinos going into service) and some remote countries will pay the toll, so no big deal.
Also it's remarkably unfair for you to cherry pick our foreign policy misdeeds while leaving out all of the good we've done over that same time frame.
I wish we cultivated a better interest in world news and culture here. Our natural borders play some (small) role in our isolation. But, yes, the population at large also ignores much of the global news.
The problem with trying to unravel the truth about Russian hacking is that both sides have similar incentives to play up the drama: For the West to paint Russia as a threat plays straight into an agenda of making Russia seem relevant and powerful. Because of that, there's no reason for Putin to try particularly hard to squash allegations whether they're true or false.
