If anything I would say that it is time to go remedy the Narsians and contain the Klem as a training and then work on exploring other galaxies to which humans can expand to without causing major conflicts. Having a world ship means also that you get to have the efficiency of a planet working on assigned tasks, making things much faster and having both the resources, energy and processing power to both create new tech, analysis of information of surveying systems and of analysing new life forms. Before that I wonder if they should show up in the star systems around their own galaxy to pose menacingly, saying that they either agree to non agression treaties or to get demilitarized for good.
