Recent research of interest groups' use of Twitter focuses on its use for intra-group member mobilization. Less has been said about social media's effects on the discourse within an issue community. Do interest groups that are part of a larger community, but whose positions divert from each other, use Twitter to engage each other? Our research explores whether groups within a defined issue community – American-Jewish organizations advocating on U.S.-Israel relations – use Twitter for dialog, or whether their Twitter networks represent echo chambers. Based on the results of our social network analysis we find the use of Twitter is more complex than the black-and-white narrative of echo chamber vs. public sphere. We find groups interact with both supporters and detractors, using Twitter's communication tools (we focus here on @mentions) strategically – but on balance the results of our analysis support a "sphericules" interpretation of social media.

Cultural diplomacy is often described as one tool in a nation's diplomatic toolbox. But the term 'cultural diplomacy' encompasses many different activities. Which of these are pursued, why, and with what consequences, are important, yet often ignored questions. Using the 2018 and 2019 Eurovision Song Contests as a case study, this article explores Israel's attempts to instrumentalize the privately-run music competition for cultural diplomacy purposes. By exalting cultural icons and connecting them publicly to their home country officials attempt to transfer the positive associations foreigners have with the cultural act to the nation as a whole. However, I posit that this cultural policy instrument is used reactively rather than strategically, and that it ignores potential negative consequences, for example a legitimization and publication of opposing forces, in this case the Palestinian cultural boycott of Israel.
