Of course they are fighting back. After all, GRU is MILITARY intelligence, that’s what military do.
This is questionable ... OK, let’s assume they can show that the hacks came from Russian intel sources ... but there is no way they can actually figure out exactly WHO (what individuals) were on the other side of the keyboards ... or did they just indict a bunch of random Russian intel operators (who will never stand trial) for publicity sake?
THOSE Russians are NOT the ones fighting back...it’s the FIRST batch that Mueller indicted months ago! KEEP UP! :)
