As long as the Scriptures say it, that is all you need, people don't want to admit to wrong doing, some might have the courage to, but that would be very few. Just as many do not want to admit to the Holocaust, it's the same everywhere, The only fact that must be remembered is that now we are in the days of judgement, and if people do not change their behaviors and thinking and repent and start praying to the true God Through his son Jesus Christ they have no hope of surviving armaggedon. And before the Memorial Christ himself was a Jew.
It's in the nature of oppression and racism. If you hate your neighbour for being better than you and correcting your mistakes what will you do? You will demonise him, lie about him and conspire against him.
Similarly, the Jews of then could not call him bad as he knew their faith better than them and then some. All they could do was deny his prophet hood and tell lies. So for the Jews of today they would have to become Christian if they apologised as they would be admitting that Jesus was a prophet and they wrongfully accused an innocent man.
The bible verse is saying as much: “Therefore let all Israel be assured of this: God has made this Jesus, whom you crucified, both Lord and Messiah.” That there can be no doubt that all of Israel's Jews are complicit in the crime of crucifying Jesus who was a prophet and the best among them.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
