Theodor Herzl wrote in 1896, more than 40 years before the Holocaust:

My happier co-religionists will not believe me till Jew-baiting teaches them the truth; for the longer Anti-Semitism lies in abeyance the more fiercely will it break out.

Herzl envisioned the founding of a future independent Jewish state during the 20th century. He argued that the best way to avoid antisemitism in Europe was to create this independent Jewish state.
