How do home‐state elites react to emigrants who form diaspora communities abroad, and how do these attitudes change over time? The article explores these questions through an analysis of the discourse and policies of Israeli elites towards emigrants who created distinct diaspora communities and established ties with local Jewish diaspora communities between 1977 and 2023. The article highlights the important role that ethnic and national identities and the prospects of emigrants’ eventual return play in such attitudinal shifts. The home state may initially see diaspora formation as harmful for precipitating emigration and obstructing repatriation and ethnic immigration. However, when it becomes clear that the return of many emigrants is unlikely, home‐state elites may come to support and even promote the formation of new diaspora communities and their ties with older diaspora communities to offset emigrants’ assimilation into their host society and increase their attachment to the home state.
