Yes, civilizational supremacism and extreme, unhinged racism have always been the foundation of Zionism. Chaim Weizmann, the true Father of Israel said in 1918: "there is a fundamental qualitative difference between Jew and Arab.”
The genocide began not on October 7 and not even in 1948 - it began the moment the phrase "The land without people" was first used.
What we see today, is the logical consequence of over 100 years of Zionist impunity in doing whatever they want. Nobody stopped them in 1918, 1924, 1937, 1939, 1947, 1948, etc...
