"We assess Moscow will apply lessons learned from its campaign aimed at the US presidential election to future influence efforts in the United States and worldwide, including against US allies and their election processes. We assess the Russian intelligence services would have seen their election influence campaign as at least a qualified success because of their perceived ability to impact public discussion.
Putin’s public views of the disclosures suggest the Kremlin and the intelligence services will continue to consider using cyber-enabled disclosure operations because of their belief that these can accomplish Russian goals relatively easily without significant damage to Russian interests.
Russia has sought to influence elections across Europe.
We assess Russian intelligence services will continue to develop capabilities to provide Putin with options to use against the United States, judging from past practice and current efforts. Immediately after Election Day, we assess Russian intelligence began a spearphishing campaign targeting US Government employees and individuals associated with US think tanks and NGOs in national security, defense, and foreign policy fields. This campaign could provide material for future influence efforts as well as foreign intelligence collection on the incoming administration’s goals and plans."

The reason why this report is important is because Russia is an unreliable foreign actor. If they're offering such overt vigorous support to a political candidate, then their motives must be called into question. It's hard to accept that they are offering such candid support on principal. It's impossible to assess whether or not Russia won Donald Trump the election, but there is no question that they helped in a significant way. If the reverse were true, it wouldn't change by concern, and it shouldn't change anyone else's. 

Let's tread carefully.
