I've lost the thread. Are you saying that the major intelligence agencies are merely blaming Russia without basis?
High confidence, about very specific things. Not all the things, i.e. the goalposts.
I'm not being mean, but honestly have a hard time understanding you. Can you explain what you mean in full sentences?
Your cited document covers a small amount of investigation not really answering his/her objections to labeling everything a Russian hack.
Nothing more to see here.
