Spiney, many wars are started on the bandwagon of historic events and rights . It worked for centuries.
There are no survivors to tell the truth and you're free to give past events specific interpretations and educate the younger generation its their historic duty to their people and heritage to do the right thing.
Past generations were drilled to obey, don't ask questions and make the family proud. Religion provided a helping hand.
Only in modern times millions of informed minds can, without risking their existence, ask publicly for those politicians to come down to earth and stop their history cherry picking. Because they just did some fact finding and its non-sense.
