At the request of Stephen, the following is as brief an elaboration of my thoughts as I can muster re: the nature of "Israel"--who is in it today, who is not, and what this has to do with that hotly-disputed little parcel of land in the Middle East.
Firstly: I do not believe in--nor, imo, does the Orthodox Church teach--what is called "Replacement Theology" by many groups in Christianity that are enamored with all things Hebrew...that is, the idea that the Old Testament Israel has ceased to be, and has been replaced by the Church. The Church does not see herself as a Second Israel, for the Scriptures teach that the Original, First Israel never ceased to be. What has happened is that, simply speaking, those human beings, be they Jew or Gentile, who have rejected Jesus Christ as the Messiah of God have been severed from the Israel of God (see Rom. 11 for an indepth description of this by St. Paul). In the same manner, then, all those who live by faith in Christ have been baptized into the Body of the Messiah, who is the Root of Jesse and the flowering of the tree of Israel.
St. Paul states it succinctly: "If ye are Christ's, then are ye Abraham's seed, and heirs according to the promise." For me--and for the Church--the idea that a group of people that have, by and large, deliberately and vehemently separated themselves from Christ for almost 2,000 years can still be called heirs of promises made to the "children of Abraham" is a slap in the face of Jesus Christ himself. Will all of the Jews come to faith in Christ? Eventually, somehow, yes, to the glory of God they will accept their Messiah and be united to Him with the circumcision not made with hands (baptism), but until then--we must be clear--they are no longer in the green wood of the tree of Israel, but rather the dry (Luke 23:31), and therefore inheritors of none of the promises made to Israel in the Old (or New) Testament, for they (unlike the Christians) no longer comprise the Israel of God, which has been carried on into the Kingdom of our Lord and of His Christ by those who would accept said Christ.
