While the Messiah was rejected by the Chosen People, God’s promise is still standing and will be realized. God did not come to the fore in Nazi Germany. The situation led to the resurrection of Israel (1948). That how God operates. The Jews are blameless. And at the final global disaster, a remnant shall be saved, including the gentiles. That’s part of the promise, the contract that cannot be reneged. It’s all there in the latter parts of Revelation. It’s always been about the Jews. We gentiles are a graft onto the promise. That is Jesus's role.
