I would say that Riina and Company waging war on the Italian State in such a spectacular fashion showed the world that they could pull it off, and showed off their sophistication and military capabilities, and I think at least partially they were able to get some of the things they wanted from the State, at the cost of numerous lives and freedoms. However beyond that, not so much. I think many would agree that Bernardo Provenzano's strategy after Salvatore Riina's 1993 capture has been much more advantageous to the Mafia than Riina's strategy.
