Today’s Germans are not responsible for the murders by their parents. That they have a sense of history and that many care for Israel is wonderful But they do not bear their parents’ guilt (as Christianity and Judaism teach).
(Exodus 34:6-7) - "Then the Lord passed by in front of him and proclaimed, "The Lord, the Lord God, compassionate and gracious, slow to anger, and abounding in lovingkindness and truth; 7who keeps lovingkindness for thousands, who forgives iniquity, transgression and sin; yet He will by no means leave the guilty unpunished, visiting the iniquity of fathers on the children and on the grandchildren to the third and fourth generations."
