Even if the damn thing worked reliably, Oreshnik is not a cost effective system, used with conventional warheads. Pooty would get a lot more bang for his buck launching standard medium or long range ballistic missiles.
The Oreshnik launches thus far served as an excellent real-world test and a demonstration of capability.
For those who say that any initial failures of the Oreshnik indicate that it is destined to the scrap heap, I would point to what many said about the Osprey aircraft when it initially had failures.
