I read in an article that if the US and British forces had not invaded North Africa and the Axis was successful, the Nazis/Arab allies would have committed genocide against the Jews in the Holy Land.

That raises another question.
If my memory is correct, the Arabs have waged (or planned to wage) three major wars against Israel.
Since multiple Arab countries were involved, it seems almost certain that agreements about the post-war division and occupation of Israel must have been prepared and signed by those nations before each war began.
Very interesting that we have never heard anything about those post-war plans.
If such plans existed and were archived, if such plans actually called for the mass slaughter of Israeli Jews, that would have incredible historical importance.
