Conclusion 201 Cross-border network ties with allies became crucial for broadcasting, representing, brokering, remitting, and volunteering on the ground. Fungible and material resources gave activists the means to augment anti-regime efforts directly and the capacity to build a new transnational organizational infrastructure. Social capital elevated activists’ voice as advisors, interpreters, and participants in the revolutions. At the same time, not all diaspora movements were equally well-resourced and able to convert resources to the Arab Spring. When movements lacked or lost these varied forms of resources, as the Syrian and Yemeni cases across the United States and Britain illustrate, their voices in the revolutions become less effective and muted. While resource conversion is a critical process for diaspora interventions, it is also insufficient to explain diaspora movements’ roles in anti-authoritarian mobilizations at home. The following chapter demonstrates how the added factor of geopolitical support is also vital in facilitating diaspora movement interventions, including the movement of resources across state lines. Without this support, diaspora activists and their resources become caged inside hostcountry borders, and their voices in homeland struggles are rendered into merely symbolic displays of support. https://doi.org/10.1017/9781009272148 Published online by Cambridge University Press
