If something has ceased to exist, it doesn't mean it didn't affect anything, I didn't mean to imply that. Like you said, the brotherhood's ancestors were a bunch of deserters from the US military, and in itself it isn't a problem. Because the brotherhood completly started over, they didn't hold on to pre war america or to the fact of being americans, which they can't be since there is no more america. They don't even speak about it, they don't care. Take a other example with the vaults, still speaking only of Fallout1/2 here. Some communities were directly started by former vault dwellers, some who don't seem to have kept much ties to their vaults, like the various groups from vault 15, and at least one who did, vault city. Do anyone in these groups even mention america or anything that hint at giving a damn about what they might have heard/learned from pre-war sources? No, people don't know or care about such former and foreign concepts anymore in the wastes, they replaced them. Sure, in many cases they only re-invented the same old humans habits, good or bad because that's how life goes but they still started anew, begin again and all that. Hell even the vault 13 dwellers don't pipe a word about being 'americans'(or insert any real world modern nationality), or how their neighbor is a 'communist' sympatizer. Compare to Vegas, or bethesda 3 for the sake of mentioning it, where vault dwellers were apparently still afraid of communists spies, name calling that between themself long after the bombs, maybe even generations after, and most wastelanders who seem to grasp what america, chineses and US meant, when they didn't have a long research history with the subject, apparently. One thing I can give to the enclave of Fallout 2, it's that at least they do seem aliens and foreign to the wastes, in this game.
