I think we're well past that now, though.
I think this is an underrepresented factor in why Israel feels unilaterally emboldened in this conflict: there's no longer a statistically more liberal, secular, identifiably Jewish majority outside of the country that serves as a check on its actions.
which isnt to say anti semitism doesnt exist or even that it isnt getting worse, just that most of the pearl clutching is being done by rather extreme racists who are pretty happy to see muslims exterminated.
Modern racial antisemitism and political Zionism were two modern political projects that grew from the same 19th century soil of nationalism and race theory. They did not agree with each other, but they converged, from opposite directions, on the same fundamental conclusion: that the Jewish people constituted a distinct, unassimilable national and racial body that could not coexist as equals within a European nation-state. Political Zionism did not adopt the idea of Jewish separateness from antisemites. It inherited this idea directly from traditional Judaism itself. The entire structure of Halakha (Jewish Law), with its dietary codes, Shabbat observance, and, most crucially, its powerful prohibition on intermarriage, was a system designed to maintain the Jewish people as a distinct, separate, and unassimilated nation in exile. This was the internal, self-defined jewish reality for millennia. Modern racial antisemitism took this existing reality of Jewish separatism and reframed it as a hostile, biological threat to the European nation-state.
The secular European Zionists looked at this situation and synthesized two ideas. Zionists accepted the traditional Jewish premise ("we are a separate people") and accepted the antisemite's practical diagnosis ("they will never accept us as equals"). They rejected both solutions, the religious passivity of waiting for a Messiah and the "liberal delusion"(as Zionists described it) of assimilation. Instead, they chose to take the existing identity of Jewish separateness and reforge it using the modern tools of European nationalism and colonialism. That's also why Zionists published scathing articles about assimilated jews whom they perceived as deluded, cowardly, and "self-hating" for trying to be part of a European society.
The leadership and foot soldiers of the early Zionist project in Palestine (1900s), were not suffering from the trauma of the Holocaust (it was decades before) and did not suffer from any meaningful antisemitism, which they also documented themselves ("the Palestinians are child-like and easy to befriend"). Zionist actions and attitudes were thus the direct, confident expression of 19th Century European settler colonialism, as evident in the writings of Herzl, Jabotinsky and co. Zionism was born in the same intellectual environment as the "Scramble for Africa" and the "White Man's Burden."
Their argument was not: "We are traumatized victims who need a safe space.", because if that had been the case they wouldn't have rejected the ugandan land they were offered - it was: "You Europeans have successfully conquered and colonized vast territories inhabited by inferior natives. We, as a superior European people currently without a state, claim the right to do the same thing as you". It was the logical, confident, and systematic execution of a European colonial project by a group that chose to see itself as a superior people with the right to displace and subjugate an indigenous population it viewed as inferior (i.e. the 'kushim' of Palestine). Those secular European atheist jews who, despite rejecting religion as superstitious and irrational, still saw value in it as essential myth-making tool to justify the dispossession of natives and legitimize their colonial zionist project by weaponizing those myths ("our God [which they as atheists didn't even believe in] promised this land to us") .
You're conveniently ignoring the Eastern European pogroms during the late 19th and especially early 20th century. Jewish immigration, in both number and origin, to Palestine not-so-coincidentally tracks the severity of the pogroms. And actually, during this time many times more Jews immigrated to New York than to Palestine. Immigration to Palestine didn't explode until the rise of Nazi anti-semitism.
Collective punishment is wrong. Full stop. Global civil society largely internalized this ethic, after millennia of accepting collective punishment as legitimate, in large part because of the experience of Jews in Europe. It's ridiculous to deny the history of how this norm came about no less than it is to deny that collective punishment has become the facial justification for Israel's war in Gaza.
David Ben-Gurion was the founder of Israel and its first Prime Minister and he confirms that: "They are nearly all good-hearted, and are easily befriended. One might say that they are like big children." David Ben-Gurion in Igrot (Letters), Tel Aviv: Am Oved and Tel Aviv University, Vol. I, 1971
And how come those pogroms didn't make those Zionist-Jews more empathetic to suffering and persecution? Instead they had the exact same racist and supremacist attitudes as the europeans they were complaining about.
"The British told us that there are some hundred thousand negroes [kushim in Hebrew] and for those there is no value." - Weizmann, quoted by Arthur Ruppin in: Yosef Heller, Bama'avak Lamedinah , Jerusalem, 1984, p.140.
I might be misreading you here, but it really sounds like you're claiming that antisemitism began and ended with the Third Reich. You're aware that's not the case, right?
I honestly don't get how one can read that sentence and come to that conclusion, but at least you already suspected yourself of misreading
