Antisemitism, history and faith

In your opinion, what is the significant factor that creates anti-Semitism in every generation, and especially in our generation?
And do you think there is a way to deal with and fight this? (Rabbi Yonatan Sachs in the attached animated video briefly presents his method from his book "In the Language of the Future" – https://www.youtube.com/watch?v=3UAcYn4uUbs&t=102s To what extent do you agree with his words?)

Continuing with the previous question, is the history of the Jewish people considered, in your opinion, to be sufficient proof to some extent for the existence of God and the truth of the Torah? If so, to what extent does it compare in terms of plausibility to the other evidence-proofs?
