“American Jews are largely pacifist...probably because of what they suffered in the holocaust.”
As I understand it, the vast majority of american jews are from families that immigrated well before the persecutions in Germany in the 1930’s started, much less the full-blown genocide and organized persecutions throughout german-controlled europe in WWII.
In addition, the Jews had no military for centuries. Thus, they had to resort to pacifistic means to get ahead. Another factor that results in much of their anti-war mentality today.
