For starters, the tendency of the Jews to be intellectuals far predates any association with Christianity. The Jews believe they have a mandate to be intellectuals because, as they like to tell it, when God rested after spending six days creating the world, he hadn't quite finished the job. So he left the final touches to his chosen people, upon whom it is incumbent to "punch above their weight," intellectually, to make sure they don't botch the job.
Then there's the matter of exile and the Jewish diasporas. The first time they were kicked out of their homeland was in the 8th Century BC, so very early on the Hebrews learned the wisdom of something my old Grandpappy told me: Always sleep with your britches where you can find them in the dark.
Because you can never tell when you might have to get up in the middle of the night and hit the floor running. And more than once the Jews have had to abandon everything they owned and leave with nothing but the clothes on their back. And whatever was contained in their brains. So they specialized in knowing how to earn a living using nothing other than their intellect. Which turned out to be a good plan because there have been a number of occasions when Jews were not allowed to own property. Which is why they have long have specialized in being banking and finance.
And speaking of Christianity, for most of their religion's existence, the Christians have been one of the chief persecutors of the Jews. The Jews, after all, did kill Jesus. And the descendants of those murdering Jews still deny him. And in denying the Christ they deny the Godhead, therefore they are Godless heathens. So they've got it coming. Several Popes (beginning with Gregory I) have endorsed their persecution.
Then there's the money-lending thing. Charging interest on a loan used to be a mortal sin under Christianity -- and still is under Islam -- so Jewish bankers served a vital interest (and Christians and Muslims alike reviled the Jews who grew wealthy from the practice). Ever read Shakespeare? The Merchant of Venice? Shylock, the money-lending Jew who demanded a pound of flesh from his Gentile customer for inability to repay a loan? Even the Bard hated the Jews.
For the most of the 2000 years the two religions have coexisted, their relationship has not exactly been ...cordial.
As for "what it did for israel and the jew in ww2," the US did very damn little. We only "rescued" them from the camps accidentally in the regular course of prosecuting of the war against the Nazis. And before that came to pass, 2/3rds of all European Jews already had been murdered.
We knew what was coming -- or should have -- after the
Night of the Broken Glass in February of 1939. After "Kristallnacht" (and the escalating refugee crisis it precipitated), two US Congressmen introduced
a bill into both chambers of the congress that would have allowed the admission of 20,000 Jewish refugee
children under the age of 14.
The bill was prevented from coming to a vote in both houses.
In 1939 the
MS St. Louis set sail from Hamburg, Germany with more than 900 Jewish German refugees on board seeking asylum in the Americas. First they made port in Havana but (under pressure from US Secretary of State Cordell Hull) the Cuban president refused to accept any of the refugees unless they had Cuban or American visas or were seriously ill. The St Louis left Havana intending to make port in Miami but the US never gave them an answer to their application to dock there. Instead Secretary Hull (with the foreknowledge of President Roosevelt) ordered the US Coast Guard to
'shoo' the St Louis away from US waters.
The St Louis sailed as far north as Nova Scotia but the Canadians refused them entry, too, so they returned to Europe. Neville Chamberlain agreed to accept 288 of them but the rest were settled in France and the low countries. Which got them out of Nazi Germany for the timebeing but left them in the direct path of the Nazi conquest of Europe. 254 of them ended up being murdered in the Holocaust.
German Jewish refugees delivered to our doorstep, free of charge, 900 of them, and we turned them away.
In 1976 a feature film was made about the Jews on the ill-fated MS St Louis titled, fittingly,
Voyage of the Damned.
By 1941, months before the Japanese bombed Pearl Harbor, the US knew a Jewish genocide was underway from two sources. The first came from decrypted Wermacht operational messages being sent by "clean-up" units following the Nazi advance toward Moscow in Operation Barbarossa. They were reporting killing hundreds to thousands of Jews who the front line units were bypassing by each time the Nazis advanced.
It was from these experiences that the Nazis decided that they should try performing executions with poison gas rather than shooting. Why? Because it was kinder. To the executioners.
The second source came from the Warsaw ghetto. In the fall of 1940 the Nazis had cordoned off a small section of Warsaw and imprisoned 400,000 Jews there. And the conditions there were essentially identical to what would come in the camps except they weren't yet killing on an industrial scale. But the Nazis already were killing Jews indiscriminately. And for sport.
By that time the Nazis were speaking to each other candidly in the presence of Jews because they had no fear of them passing any of this information outside of the ghetto. So they heard from the Nazis' own lips their plans for the mass annihilation of their people. They knew beyond a doubt what awaited them ... unless the Nazis could be stopped.
So the Jews 'allowed' some of their own to escape from Warsaw in the hope that their message would be heard and a rescue attempted. I use the term "allowed" because the Nazis were meticulous bookkeepers and every escape was followed by the retaliatory murder of dozens more Jews. So the Jews knew there was a price to be paid for the effort to alert the world to their plight.
One of those Warsaw Jews was
Szmul Zygielbojm (Sch-mool Zee-gul-boim). Zygielbojm traveled to England and the US (where he spent 18 months) trying to alert the world to Warsaw's plight. In a 1942 interview on BBC radio, he said this:
But no one acted. At least no one who counted.
In April of 1943, the Nazis 'exterminated' the Warsaw ghetto. Zygielbojm's wife and older son, who had remained in the ghetto, were among those murdered. This took place during the 10 days of the Bermuda Conference, which the US and the UK co-hosted, and at which the participants agreed to do ...nothing.
On receiving the news of his family, Zygielbojm penned a letter to the president and prime minister of Poland in which he said:
He dropped the letter in the post, went home and took a lethal dose of sodium amytal in the hope that his death would bring notoriety and recognition to the cause.
But he died in vain because the Nazis still killed 300,000 of the Warsaw Jews, either by shooting or after being sent to death camps.
In April of 1944, two Jews escaped from Auschwitz carrying with them
extensive details of the industrial-scale murder taking place there. Most convincingly they brought the label from a can of the
Zyklon-B cyanide that the Nazis were using in the gas chambers. But again their warning fell on deaf ears because by the time their message had reached England and the US, the Allied invasion of Europe was under way.
The upshot was that the Auschwitz Jews were asking that the Allies bomb Auschwitz. Not the camp but the gas chambers, which were not in the camp itself but some two miles away in Brzezinka. But they naïvely believed that WWII bombing was so precise that they could bomb the gas chambers and not endanger the camp. The Allies did examine the question but decided against it entirely because it would have diverted resources from the greater war effort.
The Allies did in fact bomb Auschwitz, once, but that was the city, not the concentration camp. The target was an
IG Farben plant engaged in the manufacture of synthetic fuel and rubber, both critical to the Nazi war machine. Ironically, a subsidiary of IG Farben also was the manufacturer of Zyklon-B but not at this facility.
The Soviets liberated the first concentration camp (
Majdanek) on 22-23 July of 1944, and then another (
Lublin) on the 24th. The Americans didn't stumble across a camp until Buchenwald on April 11, 1945.
When the Brits liberated their first camp (
Bergen-Belsen) on 14 April, 60,000 Jewish prisoners were still alive, but there also was an outbreak of typhus. Between disease and malnutrition, more than 10,000 of them died in the weeks to follow despite having been freed.
So, yeah, the US was part of the effort that prevented the Jews being exterminated, I'm just not sure God was particularly thrilled that they allowed 6 million-ish of his chosen people to murdered before they got around to it.
And the experience taught the Jews not to rely on anyone else. Particularly for their survival. So they'll take aid from the US, they just don't count on it.
EDIT:
On top of which, if it hadn't been for the European Jews working on the Manhattan project, the Nazis might have got The Bomb first. So I'm not too sure who owes whom.
