Are they Jews?
Then they are the Israel of the Bible.
According to St. Paul, the Church is the Israel of God:
Galatians 6:14-16: "But far be it from me to glory except in the cross of our Lord Jesus Christ, by which the world has been crucified to me, and I to the world. For neither circumcision counts for anything, nor uncircumcision, but a new creation. Peace and mercy be upon all who walk by this rule, upon the Israel of God."
The Jewish people of our day, beloved by God though they may still be, are simply Jews. Individuals among them are included in Israel to the extent that they are doing God's will as they know it.
