If Israel didn't exist, the enormous amount of antisemitism we are currently experiencing probably wouldn't be happening.
Between 1795 and 1918, Poland ceased to exist. After WW I, the League of Nations brought Poland back into existence, taking territory from Germany, Austria and Russia in order to accomplish the deed. This created an enormous amount of anti-Polish hatred during the inter-war period in those nations, as both Russia and Germany viewed the League of Nations intervention as outright territorial theft. Poland was seen by many Eastern European Axis supporters as an illegal state, created out of whole cloth by the Western Allies who had conquered them.
So, what was the very first act of WW II? Germany and Russia invaded Poland and repartitioned it, taking back the territory that the League of Nations had stolen from them.
That whole sequence of events worked so well, that after WW II, the UN repeated the mistake. The UN tried to bring Israel back into existence, with similar consequences. But the attempt to reconstitute Israel failed for an even more foundational reason. Poland had been out of existence for less than two centuries. Israel had been out of existence for nearly two millennia. The new Poland had never lost its majority Catholic population, but that wasn't true for Israel. The original Israel was a religious state built around Abrahamic faith. But the 20th-century version of Israel was created by secular atheists, socialists who weaponized Christian ignorance and stupidity in order to guilt the West into attempting to recreate the country. Ben-Gurion himself saw socialism and Zionism as two sides of the same coin.
Unfortunately for everyone involved, Zionist socialist ideology has nothing to do with post-Temple Judaism. And post-Temple Judaism has literally nothing to do with Temple Judaism. The current state of Israel is founded on socialism and nominalism, the idea that words are just interchangeable labels. But words mean things. As Lincoln pointed out, if you call a dog's tail a "leg", that doesn't mean a dog has five legs.
The current state of Israel has literally nothing to do with any preceding entity, much less any Biblical entity. Israel is a bullshit country that exists by fomenting antisemitism in other countries in order to force Jews to emigrate to Israel "for their own safety". Apart from redefining "Jewish" (which is also a constant work-in-progress), it was, and still is, the only way to keep the Jewish population at high enough levels to justify the existence of the country. Recall that between 1948 and 2010, the country with the largest Jewish population in the world was the United States, not Israel.
Israel can only work if Jews feel unsafe everywhere else and think their only hope for safety lies in moving to Israel. Wherever non-Israeli Jews live, Zionists must drive them out of that location and into Israel.
In December, 1938, David Ben-Gurion, one of the founders of the state of Israel, specifically said, "if I knew it was possible to save all children of Germany by their transfer to England and only half of them by transferring them to the Land of Israel, I would choose the latter, because we are faced not only with the accounting of these children but also with the historical accounting of the Jewish people." This was not just rhetoric. In 1945, Ben-Gurion and other Zionist leaders vetoed the immigration of 1,000 orphans from Germany to England, even though the necessary permits had been secured and these children were in grave danger of death due to the harsh winter. Zionists also managed to stop another group of roughly 500 children from reaching France, where rabbinical institutions had offered them safe haven.
As 1930's Germany demonstrated, the best way to drive Jews out of an area is to make it impossible for Jews to live there. Antisemitism serves the political purposes of the state of Israel. Antisemitism is a nation-building activity for the state of Israel. Zionism is functionally antisemitism run by a nation-state actor for their own political purposes. Seeing the Zionist success, Palestinian-wannabees imitate it. This is why both the Muslims who attack Israel and the Jews who defend it are so politically insane that both sides literally sacrifice their own children in order to attain their nation-state objectives.
Parents who care about their children move to safe locations to raise them. Israel is not a safe location. Only politically insane people would move to Israel/Gaza/West Bank, or stay there, to raise a family. Raising a family in that area necessarily involves you, as a parent, to be willing for your own children to be killed so that the greater good of the nation-state can be attained. This attitude is purest socialism, the elevation of the state above everything, including the family, just as Marx and Engels commanded.
But this is not a surprise. Again, most people in the 21st century forget that Israel was founded as a socialist state. Most conservatives, especially Christian conservatives, find it impossible to grasp that nearly all modern Jews are extreme leftists, generally socialists. Jews always vote for the most extreme left-wing candidate available. Christians are so blinded by Biblical references that they literally cannot see that post-Second-Temple Jews are not Biblical Jews, or that the 1948 socialist-founded state of Israel is nothing at all like ancient Israel.
Christian conservatives created the phrase "Judeo-Christian morality" in order to facilitate conversion of Jews to Christian faith. It didn't work. But the Christians used their invented phrase so frequently that they successfully fooled themselves into thinking there was some commonality between Jewish and Christian worldviews. In fact, Judaism shares as much, if not more, of a worldview with Islam than it does with Christians. Jews can worship in mosques, but not in churches. Most medieval rabbis agreed that Jews could pray with Muslims, but not Christians. According to this Jewish expert, the Torah says Jews must kill Christians. Jews and Muslims share a morality that Christians consider self-centered, even bordering on narcissistic.
Zionism is antisemitism. Period.
