You are referencing ‘Replacement Theology’.
I believe this to be a very wrong belief and here is one location that more fully discusses this:
http://www.therefinersfire.org/replacement_theology.htm
I am referring to "Fulfillment Theology". Replacement Theology is a pejorative term that does not reflect traditional Christian teaching on the relationship between Christianity and the Jews. In short, Jews have not been replaced but rather gentiles, as was promised by the prophets, have been grafted on to Israel in the New Covenant in Jesus Christ. Two thousand years ago some Jews accepted Jesus as the promised Messiah and welcomed the gentiles into their community. Other Jews rejected Him and continued to separate themselves from the gentiles. In Jesus Christ the Jews have not been replaced; the Covenant is opened to them in union with all mankind. Jews and gentiles are united in one Covenant with God; there is no separate Covenant for the Jews only.
In any case, it was not my intention to highjack this thread and redirect it to this issue. I just wanted to be honest and state my position as I addressed the the question at hand about what I see as a dangerous presumption that God will alway see Israel victorious and in possession of the land despite its own non-observance of the Covenant.
