Who must be killed to defeat ISIS and Al Qaeda?

We kill leader after leader. The high profile targets and each time someone new steps into their place. They change their names (Abu Khalil Al Sudani), to try to hide their identities and still we kill them. They hide (Osama bin Laden) and still we find and kill them. Each time it seems like a victory until the sun rises and then someone new is standing in their place. ISIS is no longer a terrorist organization. It is Political Entity that has an Army and it operates like an organization (company). How do we fight a state? We learn about how it operates and we understand the threat. To defeat ISIS we must destroy it's critical capabilities and the ideology that goes with it. We have to go after the money that is funding it. The people that are living under the feudal reign of ISIS are becoming disenchanted with the idea of fundamental Islam. We need to exploit this.
