Executive Summary
Roughly one million ethnic Lithuanians live abroad against ~2.8 million in Lithuania. The largest hubs are the United States (about 650,000, centred on Chicago, Boston and New York), the United Kingdom (about 200,000), Ireland (about 40,000), plus communities in Norway, Germany, Brazil and Argentina. Scaffolding exists: the Worldwide Lithuanian Community, the Joint Baltic American National Committee (JBANC) for US lobbying, diaspora voting rights, and the National Defence Volunteer Forces (KASP) for volunteer reservists. None is wired into a defense channel for fundraising, skills, advocacy, or crisis return. Foreign references exist. Ukraine's United24 platform reportedly raised over one billion dollars since May 2022. The Chatham House Super-Sparta analysis of April 2026 flags Israel's reservist model as under strain. Estonia's e-Residency is a smaller digital comparator. The recommended next step is a Ministry of Foreign Affairs and Ministry of National Defence feasibility study, with diaspora and Seimas input, mapping legal authorities, KASP returnee pathways, and a realistic fundraising envelope. The vehicle is for Lithuania to determine.
The Problem
Russian information operations target Western capitals where the Lithuanian diaspora is concentrated. Lithuanian-American advocacy through JBANC has historically shaped US Baltic policy, but coordination across hubs is uneven. Ukraine's experience after February 2022 showed that diaspora fundraising, equipment donations, and lobbying can scale fast when a single trusted channel exists; absent that channel, effort fragments.
No single defense-focused diaspora platform; fragmented organisational landscape across the Worldwide Lithuanian Community, JBANC, the Lithuanian-American Council and country-level bodies; no skills-to-defense-needs registry; no pre-registered KASP returnee track for diaspora reservists; fundraising is ad hoc rather than tied to specific equipment goals; advocacy in NATO capitals is uncoordinated.
Without action: Latent fundraising and advocacy capacity stays unrealised; second-generation diaspora drift away from Lithuanian institutions; in a crisis, returnee mobilisation is improvised rather than pre-planned.
Lithuanian Context
Lithuania already has the constitutional and organisational scaffolding for diaspora engagement (Worldwide Lithuanian Community since 1949, JBANC since 1961, diaspora voting rights, KASP for volunteer reservists). What is missing is a defense-specific channel and a returnee-reservist pathway. Whether to build one platform, expand the Global Lithuania programme inside the Ministry of Foreign Affairs, or layer a defense annex onto KASP is a Lithuanian determination.
