It's presumptuous to definitively say it was Russian hacking that initiated the leaks.
The Democrat spin-meisters/slanderers like to front a lot of assumptions as fact to smear Trump.
Several dots fronted, that no one has factually established a connection between yet:
1. That the Russians did the hacking (THAT one may be true)
2. The reason the Russians leaked the documents was to help the Trump campaign. (Wild Democrat-partisan speculation, absolutely no proof.)
3. The Russians wanted to help Trump because he is weaker than Hillary regarding NATO, and she alleges Trump wants to end NATO (which is a flatout lie, Trump wants to pressure members to pay their agreed to share of NATO military costs, and not leave the U.S. with 72% of the tab, as they have for decades. So Trump is not weaker on NATO.)
And most offensive and slanderous of all, speculated one DNC talking head:
4. That the Trump campaign was somehow in collusion with the Russians.
NONE of these have a shred of evidence to support them, only similarity to Russian techniques on (1) can be plausibly speculated based on anything.
