Nolte's opponents have expressed intense disagreement with his evidence for a Jewish "war" on Germany. They argue that Weizmann's letter to Chamberlain was written in his capacity as head of the World Zionist Organization, not on behalf of the entire Jewish people of the world, and that Nolte's views are based on the spurious idea that all Jews comprised a distinct "nationality" who take their marching orders from Jewish organizations. Lipstadt criticized Nolte's thesis on the grounds that first, Weizmann had no army in 1939 to wage “war” against Germany with, and that Nolte had totally ignored the previous six years of Nazi persecution of the Jews, making it sound like as if Weizmann had struck a low blow against Germany for no apparent reason in 1939. Furthermore, it has been contended that there is no evidence that Hitler ever heard of Weizmann's letter to Chamberlain, and that it was natural for Weizmann, a British Jew, to declare his support for his country against a fiercely anti-Semitic regime.
