to answer your question: parts of israel may be ancestral homelands - but not only to the jews. There were people there before the jews arrived 9according to bibble accounts, which are no doubt, mythologized tales told centuries later). The modern day palestinians may well be descendent from 1.) jews (highly likely - check recent DNA publication showing indistinguishable dna of palestiniasn from that of the jewish inhabitants 2.) philistines (or sumerian or other natives) 3. the land is ancestrally beelonging to jews who fell from grace for a reason. So what makes them any more deserving than people who lived there for the past several hundreds of years? The palestinians do appear to be a distinct people from other arabs (bedouins, egyptians etc.). So they discovered that they must have their own country on their own land, which you happened to conquer. Your claim to your "ancestral homeland" is hereby rejected on the basis that your own god saw fit to send you away. may be this god knew what it was doing, ha?
