Zionists audaciously propagandize that WW II proves that Jews need their State. In fact, it really proves just the opposite (besides for the Zionists’ various misdeeds during and after WW II which indicate the egregiousness and chutzpah of their terrible lies regarding WW II).
Zionists wanted and continue to want to change our people’s very identity from a people of the Torah (even the Muslims refer to us as people of the Book, al-khitab) to, CH”V, one based on a Nation-State.
WW II proved decisively that assimilation never works, even in the most enlightened of nations of the time, in Germany. Obviously, the churban there extended to Jews of all stripes, as noted. Also as noted, the double-standard applied to Israel seems to prove the same thing about assimilation.
But it is Hashem that is our shield and protector; and the Torah of Yaakov, not the sword of Eisav, is our pride and joy and strength which has kept us throughout the generations and will always keep us, BE”H, ad beas goel tzedek BB”A.
