But you forgot something. I said that the above about the Enclave accepting pure wastelanders would be under Colonel Autumns command. Then that makes SENSE. OMG, I never realised it. But Eden set up Colonel Autumn and kept his plans under the radar by asking Autumn to expand into the wastes and keep him busy with field operations while Eden reversed engineered the FEV Richardson had so he could await the moment the Colonel captures the LW and use him in his plan to purify the wastes. All that while the Colonel was in a deluded campaign of propaganda and expansion. By god, I've got it!!!
That sounds... uh, mostly correct.
Colonel Autumn turned out to be against the genocidal modified FEV plan, but that makes him an exception in the Enclave, not the rule... a renegade, if you will. The Nazi Party is a real-world historical group which the Enclave is loosely based upon, and although not every single Nazi necessarily agreed with Hitler's goals (a few tried to assassinate him, and some secretly helped Jews escape persecution [Schindler's List]), nevertheless the party as a whole was still attempting to commit genocide against an ethnic group.
