Much of the literature on ethnic lobby groups comes from either research on interest groups or ethnicity that looks to foreign policy cases, or foreign policy analysis studies that focus on the role of interest groups or ethnic groups. In the 1970s and 1980s, there was a burst of scholarly activity regarding ethnic interest group activism in US foreign policy, following the changes in American society and in the US Congress that emerged from the wake of Watergate, Vietnam, and the civil rights movement. Later, the end of the Cold War brought a new burst of ethnic lobbying on foreign policy, and a new wave of scholarly attention to these issues. During both of these bursts of attention, studies predominantly focused on the activities of the American Israel Public Affairs Committee (AIPAC), which was often seen as an exception to the rule that interest groups are not very significant forces in the foreign policy sphere. Another source of research on ethnic issues and foreign policy is the emerging literature on ethnicity, the construction thereof, and the political development of ethnic communities over time. The three basic issues that stand out in the literature about ethnic lobbying on foreign policy include the formation of ethnic interest groups, the roots of ethnic interest group success, and whether ethnic lobbies actually capture policy in their respective areas, at least in the context of US foreign policy. Meanwhile, the two level game perspective and the competition among ethnic groups needs further exploration.
