I will not go into too much detail on this matter. The ideas speaks for itself as if you investigate many resources within the organization can be reallocated to NGA and NSA and space based management can be fully taken on by the Air Force. The organization no longer can justify it's existence when you look at how much money you can save by getting rid of it.
Once again, this would be a disband and reallocation of it's resources to existing Agencies who deal directly with the type of work the NRO does. Get rid of the middle man essentially.
