Can't actually prove it, except by circumstantial information.
1. Circumstantial evidence is not proof. So this is not an "except by" case.
2. Okay, then give me all the circumstantial evidence that the Israeli lobby caused the Iraq war. (By the by, you know Israel has long been more worried about Iran than Iraq, yes?) And I don't mean give me circumstantial evidence that the Israeli lobby
pushed for the Iraq war - many other lobbies did as well, as did most of the American people. What I want is specific evidence that they were the
cause. That the idea did not exist before the Israeli lobbied pushed it, or, at the very least, that the idea was not at all popular until the Israeli lobby pushed it and became popular specifically because the Israeli lobby pushed it.
However, there is a lot of information out there on the role of Jews in sublimating the antisemitism in the US and creating an atmosphere congenial to Jews by gradually making Jews "Americanised".
I think you enjoy being mocked and receiving anger from others on this site for your opinions. You have that Rush Limbaugh like quality of saying things that are totally irrelevant, ignite emotions, but are not actually crossing the line of being legitimately offensive or too far. This idea in your post - that Jews became "Americanized" - is a very good example of that.
(1) It has nothing to do with the original post or what I said.
(2) It singles out one group as if the quality you attach to them is unique in the situation. It is not. Almost every group that has come to America has become in many ways "Americanized". And America has become "them-ized". America has been shaped and helped shape it's immigrants for more than a century.
(3) It is worded as an insult would be worded, yet is not actually an insult. It generalizes, but without being necessarily offensive.
Allow me to be more clear by example.
There is no conclusive proof that the Moslems control American policy towards imported feta cheese. However, there is a lot of information out there to show that the Moslems have become more "Americanized".
Do you see what I mean? The two halves of the above statement have absolutely no relation. Yet are phrased as if the latter supports evidence of the former claim. And since the claim in your example is - by most - considered to be a negative against the subject, it comes off as being racist (or anti-jew, or whatever term you choose) without actually quite being so. In short, you get to push a quasi-anti-jew sentiment without suffering the moral pratfalls of actually making an anti-jew statement. It's good rhetoric for making debate partners pissed off, but it's poor logic, poor writing and poor sport.
Most people who love debate and feel passionately about an issue seem to also enjoy the "martyr syndrome". That is to say, they take a certain pleasure out of having certain groups of people deride, criticize or hate them. (I myself, from time to time, am quite guilty of this). You seem to fall into this category. Repeatedly I've seen you respond to childishness with even greater childishness; respond to ignorance with willful silence, contempt or pure criticism bordering on elitist derision.
It would serve you better to cut it out. The best reason is because it's ineffective. If you have a goal in mind, you ought to be working towards that goal, not hindering yourself. The second reason is just general self honesty, which is always a good thing, and holding yourself to the highest standards. The final reason that applies to you is that I simply doubt God would commend such behaviour. It's been a while since I've read the Quran, but I don't recall reading "thou shalt respond to infidels with deceptively false logic, trickery and insults."
It would be difficult for anyone to believe that just 100 years ago there were only a million Jews in the US, almost half of whom were newcomers.
In 1920 the population of America was about 92 million (and change).
In 1920 the Jewish population of America was about 2 million (and change).
In 2008 the population of America was 305 million (and change).
In 2008 the Jewish population of America was about 5.5 million (and change).
From 1920 to 2008 the population of the country increased by ~2.3 fold.
In that same time period the Jewish population increased by ~1.74 fold.
In 1920 Jews made up ~2.1% of the population.
Today they make up around ~1.9% of the population.
In short, nothing is surprising about the relatively minor rise in number (though not representative percentage) of Jews in America. Most other minority ethnic and religious groups have climbed in number and importance much more than the Jews did.
