Every state/nation/collection of sentient beings by modern human standards should be given aid to reach some semblance of minimum civilization and liberty compared to the best in the world.
If after 200 years of continous aid, they are still unable to achieve that, they should be disbanded.
Population replacement, existing population ideological and contributory review and existing population dispersement must be undertaken.
If there are elements with extreme negative contributions, they should be identified and eliminated.
Growth and goodness work best with review and ruthlessness.
