Russia for sure has helped Trump to win the election by playing a big role in email hacking event. Russia won't do it for free. There must be a secret deal between the intelligence of two countries. We outsiders can only see it from some facts.
The secret deal: Hacked email were handed to Wikileaks to issue to hit Hillary Clinton.
The payment of secret deal:
1. Aleppo falls (or "liberated" from Russia side) on 12/15. Resistance and civil withdraw from East Aleppo by bus. Five years fight ends. A big victory for Russia and its allies.
2. Economic interest.

Putin dismissed the notion that he was only interested in getting economic benefits from Japan.
"If anyone thinks we’re interested only in developing economic links and a peace deal is of secondary importance, that’s not the case," he told the same news conference. That's all for the controversial islands. He went Japan just for those business deals.
You may say that's something between Russia and Japan. The Truth is Japan is the pocket slave of the US. If you still remember Trump claims credit for $50 billion investment by Japanese firm and 7 billion from a Taiwan firm. They were puppet nations that have to pay their defense share that Trump demands. Include that payment to Russia for the US sake.
