The US government was run by the descendants of the reptilians from the planet Nibiru, who were accidentally brought to Earth tens of thousands of years ago and lost their technologies. Therefore, all US space programs are aimed at building a sufficiently powerful spaceship and returning the reptilians to Nibiru. All vaults and experiments with the virus of accelerated evolution are needed only to simulate the conditions of a long flight and the ability of people (or their genetic modifications) to reproduce in several generations to service the reptilians, who will be in a long cryogenic sleep for hundreds of years. The death claw is one of the service options, carrying part of the reptilian genome.
