Your question is about the jews but it applies to the
arabs who left in 48 also, why should they be allowed
back, they left too.
Why don’t we stick to the issue about making claims on a piece of land that was abandoned for 2000 years and the consequences of supporting the claim without carefully thinking out the process like what do you do with the people who are living there??? Nobody asked the Palistinians if they care, and no one thought what would happen if we ignored them? I think we already have the answer. If this issue had been properly decided, we would not be wondering if the Palistinian who left or fled in 1948 have the right to come back and reclaim his land/house in Isreal. One thing I learn from studying history, you do not mistreat people because today they are backwards and powerless, because in the future they may not be backwards and powerless and will come after you for past wrongs.
