Literally the entire date / time setting of the show is arbitrary. If they want to leave the canon of NV intact they would made that date later, though like I said, even if they do that, they’re still undermining the narrative themes of NV by nuking the symbol of hope off the map right afterwards.
“No they didn’t because I like the show so nuh-uh” is not only a boring an opinion but one backed up by nothing.
