I’ll give you the specific detail as to why this particular accusation is not credible.
Note in the article, almost all the quotes - especially the key ones - are from anonymous “officials”.
Of the three people who are actually named, NONE of them make the accusation that the article makes.
So the question is: who are these unnamed US and UK government officials who are making the accusation? I’d wager that they’re all Clintonites or Deep Staters with mischief on their agenda, and this would be obvious if they were named - so they are not named.
Bottom line: to believe this accusation you have to take the word of anonymous government “officials” - the well-known hallmark of fake news.
Even if it were true, doesn’t every major power have cyber units that try to attack the enemy via the internet ?
I know we do.
