1. The jewish elites you see in history - the ones who appear as if their removal would undo postwar jewish dominance - were just the jews who did the thing. They act solidaristically and decentralized. Get into a time machine and kill Jacob Schiff: some other big money jew would be in your book as the Wall Street jew who financed the Bolsheviks.
2. Whites were susseptable long before jews kicked it into gear. What you're looking back on is an unregulated social space where antisemitism wasn't prohibited. Not a social space where antisemitism was a significant driver of public sentiment. The fact that Ford and Coughlin were taken down - at enormous effort - shows that antisemitism was not popular among white elites. Indeed, British Zionism was more influential than antisemitism.

The Church and Hitler didn’t tolerate degeneracy while America tolerated it. Once you tolerate a subversive element it will use that tolerance to push the boundary further and further until it has completely taken over society.
The Jews took over America because secret societies and Jews were tolerated. They may have been shunned but they were still permitted to exist.
Subversion, infiltration, and take over isn't done in one big step. It's done incrementally, in small steps over time. Jews gain power, historically, through banking institutions and controlling the money. This indebts them to very powerful people at the upper echelons of society. This enables jews to control those people and the upper echelons of society, so they can steer policy and decisions, and to infiltrate those positions and institutions through their undue influence. Once those institutions are captured, they push outward and infiltrate, subvert, and control more institutions. Through this method of incrementalism, they now control almost every aspect of Western civilization. Many people don't realize it because of the massive amount of propaganda and control/weakening mechanisms arrayed against us.
White people build naturally high functioning high trust societies. We don't act in the way jews do, so we're not immediately cognizant of their destructive behaviors, idea, and lies. Their behavior is anathema to the health, longevity, success, or righteousness of any group their inhabit, so it's difficult for decent people to predict for it, spot it, and root it out. Don't forget that much of what jews offer, at face value, seems beneficial in some way. We can see this immediately with people's current views on usury. Usury isn't just high interest loans, it's loans with any interest. The current logic is "why would anyone loan out money without interest, some benefit to the loaner?" This, at face value, makes sense. However, as we plainly see, usury has deep problems that are philosophically and historically too dangerous to employ. It creates wealth from nothing, which is the enemy of productivity. It concentrates wealth in the hands of the lenders, the bankers, the people that control the money. It forces people into a never ending death spiral of pursuit of money (i.e. mammonism), which is exactly what the West is currently experiencing, from top to bottom. And even though the poisonous fruits of usury, and those that employ it, are becoming plainly apparent, right wing normies, even Christians, defend usury because of the surface level reasoning, and the propaganda acts as a deterrent for people waking up to the truth.
Don't forget, too, that jews shapeshift. They always give themselves away, if you know what to look for, but they try to blend in with their host group, to better subvert it. This is why they always use arguments like "fellow _____, we must _____, or we won't survive" when they're in the small minority, or have little power at the beginning stages of infiltration and subversion. But, when they gain undue power over a group, they speak and act more brazenly, openly bragging about their subversion, lies, murder, and destruction. Liars manipulate people. Jews are skilled liars and word smiths, enabling them to bullshit their way out of tough spots, to twist meanings, and to manipulate people. And on top of this, they're nepotistic, so their lying serves their in group, while destroying their host.
