That Jews are promised a homeland does not have to get them to take the land from others. They always should remember we are tenants of the Land of God and always do we have to respect all inhabitants of God's World. People living outside Palestine and Israel should see those caught behind walls as real, living breathing human beings rather than either incorrigible terrorists or unthinking puppets of Hamas.
After World War II the children which were placed in Catholic families often found no Jewish families to take care for them or to bring them up in Jewish traditions. Most of them even did not have the opportunity to learn Hebrew and got estranged from Jewish traditions. They married and got children who started to wonder about their ancestors. Several of them also wanted to go back to the Jewish culture and found stronger bounds with Jewish religion, whilst others wanted to keep their faith in the Messiah, but did not want to be counted under the trinitarian Christians.
