From the New York Times of December 9:

WASHINGTON — American intelligence agencies have concluded with “high confidence” that Russia acted covertly in the latter stages of the presidential campaign to harm Hillary Clinton’s chances and promote Donald J. Trump, according to senior administration officials.

They based that conclusion, in part, on another finding — which they say was also reached with high confidence — that the Russians hacked the Republican National Committee’s computer systems in addition to their attacks on Democratic organizations, but did not release whatever information they gleaned from the Republican networks.

In the months before the election, it was largely documents from Democratic Party systems that were leaked to the public. Intelligence agencies have concluded that the Russians gave the Democrats’ documents to WikiLeaks.

The Republicans, naturally, deny that their networks were hacked. To which the answer is: how would they know?

This story merely confirms what we have intuited for ages, namely that Russian investment in the disruptive potential of the Internet (as part of the ‘Gerasimov Doctrine’) is now beginning to pay off.
