[Regain control of Wanghai from the mutants?]
Needless to say, it was a tempting proposal, and the current NAC certainly had the capability to do so.
Wanghai from before the war wasn't only the center of PAC's economy; it was the industrial base for technology. If NAC could regain control of Wanghai, the speed in which the pre-war technologies could be recovered would be much faster.
But then another problem had to be considered.
The mutants did indeed threaten the lives of the survivors, but the crystals they provided were the foundation to survivor industries. The Sixth Street's power station required crystals, the fuel rod used for everything from vehicles to power stations required crystals. Survivors unable to obtain Helium-4 to produce nuclear fusion batteries had to use crystals to produce fuel rods with the same specification to provide power to pre-war equipment.
Fallout Shelter 027 was currently using this fuel rod.
