Palestinians reject invitation to attend US Mideast meeting in Poland

The topic I introduced was DNA -and the fact that as should be expected that the Ashkenazi is 99% European and 0% Middle Eastern. The Jews claim was based on being the descendants of Abraham. Is it possible they could b descend from Abraham if they are 99% European? You did not refute the DNA results, did you? If you did not dispute them means you accepted them as true and valid and yet, you turnaround and say a people who are 99% European have a right to that land? Based on what?
