Happy to say the 6.6% of those who can show legal documentation of a valid purchase should stay unharmed (as long as they aren't military combatants of course). 6.6% is not of course and quite far from 100%.
Where are the rest? The ones who don't have legal papers of purchase and whose immediate ancestors 2 to 3 generations back are in Europe? How do you think they managed to squat on land that isn't theirs, where they never lived in, and where they didn't have any legal deeds of sale?
