Origins/Major Influence: Zild's post in NS Alpha Complex Alliance To Promote Complexism Via UN, Alpha Complex as Members of the United Nations (require access to Paranoia-Live's GM Meeting Room)
Description: There was a reason why the Polity existed in the first place. A world government would provide prosperity and security to each of the individual Complexes, preventing inefficient duplication of the same service groups, and increases the happiness and morale of everyone involved by laying down a set of common laws and standards to protect so-called "human rights" (the right to have a job, the right to have a daily supply of happiness pills, the right to have oxygen, etc.). Even after the Catastrophe, it would make sense that the world government would be reformed, with several Complexes banding together for the common good. But, each Alpha Complex desires at least some sort of autonomy and sovereignty, so rather than bringing back the Polity, the Old Reckoning concept of the "United Nations" is brought back.
Alternatively, there was no Catastrophe to begin with. Alpha Complex is just a strange, abnormal despotism within a relatively non-paranoid modern day world, and the whole propaganda of WW3, the Polity, and the Catastrophe was made up as a part of cynical attempt to prevent emigration. Alpha Complex's superior military technology makes it a famed weapons dealer, but unfortunately the whole "insane dictatorship" gimmick also makes Alpha Complex very unpopular in the international community. In this setting, the United Nations functions as it does today: a somewhat impotent body that has some political power but is generally ignored by its memberstates.
The important thing to realize in either setting is that your Alpha Complex is not a member of the United Nations, or if it, is an isolated, fringe one at best. Alpha Complex cannot do anything against the United Nations, because it knows that the UN will squash it like a bug. The most it can do is build up enough deterrence to prevent the United Nations from imposing its will. For its part, the United Nations is not particularly interested in military invasion, but it does want Alpha Complex to eventually join up and adhere to its laws like a good member-state. Alpha Complex will at least feign adherence to those laws, and will present happy INFRAREDs and high-clearance delegates as propaganda vehicles in a desperate attempt to fool the UN.
Spy From Another Alpha Complex: These are "inspectors" sent to examine the conditions in Alpha Complex and possibly pressure the government to adhere to international law.
