 According to Mitchell Bard, the two Jewish groups aim to present policy makers with unified and representative messages via the aggregation and filtering of the diversity of opinions held by smaller pro-Israel lobby groups and the wider American Jewish community.The diverse spectrum of opinions held by American Jewry is reflected in the many formal pro-Israel groups, and as such some analysts make a distinction within the Israel lobby between right-leaning and left-leaning groups.This diversity became more pronounced following Israel's acceptance of the Oslo Accords, which split "liberal universalists" and "hard-core Zionists—the Orthodox community and right wing Jews".
