June 25, 1933, Jehovah’s Witnesses organized a convention in Berlin, Germany. Some 7,000 persons assembled and publicly presented their intentions. A formal letter to Hitler called the “Declaration of Facts” was unanimously accepted by all Jehovah Witnesses at the convention. The letter stated that they were politically neutral, but it also referred to points on which the JW’s and Nazi Party were in agreement on.
Regarding Jews, the Declaration stated: “It has been the commercial Jews of the British-American empire that have built up and carried on Big Business as a means of exploiting and oppressing the peoples of many nations. This fact particularly applies to the cities of London and New York, the stronghold of Big Business.”
In a separate context the Declaration, stated: “Instead of being against the principles advocated by the government of Germany, we stand squarely for such principles and point out that Jehovah God through Christ Jesus will bring about the full realization of these principles and will give to the people peace and prosperity and the greatest desire of every honest heart.”
I’m not sure how much JW’s have actually tried to hide this issue. All the above was excerpted from a Wikipedia article.
