Just a thought… imagine if a huge number of people descended from the Irish diaspora decided to return to Ireland, not just as immigrants but as colonists who then took over the government, displaced large numbers of the current inhabitants, and then forced the remaining existing population of Ireland to live in a small enclave, which they then bombed repeatedly, while persecuting any of the current inhabitants in the settler zone.
The Irish diaspora were forced to leave Ireland because of horrendous colonial policies and events like the Great Hunger or Potato Famine (in which 1 million Irish people died—an eighth of the population of Ireland at the time). They have their own distinct culture and religion. And they were persecuted in the countries that they were dispersed to.
So would they be “entitled” to return to Ireland and take it over lock, stock, and barrel from the current inhabitants? Of course not.
