If it's your heritage, that's fine, but we are American's and America comes first. I am Italian, I don't hold some special bond with Italy or Rome.
From a Christian perspective, many Christian denominations identify Israel as God's people. They are not God's people, Christians are.
They WERE God's people, they crucified Christ, knowing He was the Messiah. They knew what they were doing as they shouted "We have no king but Caesar."
"Neither Jew nor Gentile, bond nor free, no one comes to the Father except through Me." -Jesus Christ
They, as a people, will not be saved, until Christ's return, and they lost any bond they had with God the Father.
