God punishes Babylon. Yes, he used them to teach a lesson to Israel, but after all, Babylon itself is a wicked nation. And God restores Jacob and lets Jacob taunt Babylon. God’s heart is fixed on Jacob, his children, always. Sometimes God disciplines his children and his people, but that’s exactly because he loves them and wants them to love him and be like him. Those who believe in Jesus are God’s children and his people. Eventually, God wants us to be able to taunt our enemies. He destroys them himself for us. God is on our side. He is a Father who loves his children. No Babylon can destroy us. They might be used by God to transform our hearts to love God and make us more loving, but they can never completely destroy us. God loves us.
