European Jews (Ashkenazis) were severely persecuted by Russia, Germany & other European countries. After WW2, the country of Palestine, newly liberated from the Turkish (Ottoman) empire & under British mandate, was partitioned as a homeland for the Jews.
The understanding according to the "Balfour Declaration" was that the rights of the indigenous people would not be violated. However vast numbers of Palestinians, Muslim & Christian have been & are being displaced without mercy. Their livelihoods, farmland, homes, water supply, olive trees are all being destroyed or taken over.
Some Christians believe that that event was OC prophecy being fulfilled & that the Jewish state should recognised as "Israel" & be recognised as the "promised land" inhabited by the physical descendants of Abraham as a "holy nation. "We have to bless them so we will be blessed." They say Palestinians should get out.
Such reasoning is a rejection of the fulfilment of OC prophecy by Jesus & the Gospel Church formed when many thousands of Jews repented at Pentecost & after. True Israel continued as the Church, initially formed only with Jews, but after a few years Gentile become Christians also without becoming Jews. The physical nation of Israel was brought to an end in AD 70.
If Scripture has anything to say then this is relevant -
Ezek 47:21 ‘You are to distribute this land among yourselves according to the tribes of Israel. 22 You are to allot it as an inheritance for yourselves and for the foreigners residing among you and who have children. You are to consider them as native-born Israelites; along with you they are to be allotted an inheritance among the tribes of Israel. 23 In whatever tribe a foreigner resides, there you are to give them their inheritance,’ declares the Sovereign Lord.
