You bet your bippy they have the right!Simply that MOST of the Jews were driven out by the Romans (through slaughter, enslavement, forced deportation, etc.)...
Enough to make a mockery of your foolish idea that the Jews, by-and-large, as a People, left Judea of their own free will...
And that is sufficient to the day, and to our purposes here...
many jewsd lived in the roman empire and greece eben before their exile after the jewish wars.
do those jews too and tbeir descendants have a right to return to palestine and take over the land?
