First of all, not only did Russia launch a rocket at the moon, but it furthermore hit the moon too (at extremely high velocity lol).
Second of all, it is very literally much more difficult to even get a projectile onto a course that will merely intersect the moon at all than it is to hit any point on the surface of the earth, just in terms of raw mathematics, physics, and engineering.
Russia very much IS capable, with utmost certainty, of striking anywhere on the face of the earth, anytime they choose to do so.
The only reason they have not struck is because they have not chosen to.
(The reasoning behind the current state of that choice, however, is beyond the scope of this discussion.)
