AD730 is long enough for anything to be real
Yep, and Poland should use the same genetic testing if we're going to bring back our bretheren from Siberia and Kazakhstan and treat them as our own. (long overdue.) Give them benefits of being part of the mother country that the germans have done for decades.
As a sidenote i'm not particularly a fan of genetic testing but in Australia we've had an influx of fake Aborigines, claiming what's not their birth right, especially in academia.
I want every descendant of every Pole that was put in a cattle car by stalin and shipped to Siberia and Kazakhstan to have the opportunity to return to Poland, and to have government support to learn Polish and start a family and business etc.
