Russia wants to regain its 'superpower' stauts and thinks by undercutting America is the way to go, it really is not a bad plan from their point of view.
Russia has never been a friend to the United States, and never will be.
It is really subjective. One can argue they were a friend from 1940-45. IN the end, nations are not friends. They merely have intersections of commonality at given times.
