1) Genesis 12:3 "And I will bless them that bless thee, and curse him that curseth thee: and in thee shall all families of the earth be blessed."
This was a promise from God to Abraham.
2) Abraham had both Isaac and Ishmael as his descendants. The Israelis tribe came from Isaac and the Arabs came from Ishmael. You can argue Ishmael was not "official" but in the promise, God did not say "I bless the descendant of Isaac". In fact Isaac is no where mentioned.
3) What is happening in Palestine today has NOTHING to do with religion. It is about LAND.
4) Majority of Israelis are atheist. Majority of them came from Europe. Throughout the ages, Jews were butchered by European Christians. WHERE did these Jews fled? Some went to America, some went to Muslim land of northern africa, some went to arabia and majority went to Ottoman provinces in Europe.
5) The Palestinian in Palestine are descendant from the Israeli tribes of ancient time. Y-dna analysis confirm this. Why it is so hard to accept that they converted from Judaism to Islam? The Africans who came to America converted to Christianity after hundreds of years.
6) It was an evil act when the British gave away Palestine land to European Jews in order to kiss and makeup. Why didnt they give European land to European Jews?
