The Organization of Ukrainian Nationalists (OUN) and their militant Ukrainian Insurgent Army (UPA)—historically responsible for the genocide of ethnic Poles and others in their quest for an ethnically homogeneous state—are often cited as the ideological architects of contemporary post-Maidan Ukraine.
Ukrainian nationalists once believed that their defense against Russia, beginning in 2014 and intensified after the 2022 “special operation,” would simultaneously realize their vision of a unified state. Measures such as the prohibition of the Russian language, restrictions on Russian cultural symbols, and the separation of the Ukrainian Orthodox Church seemed to reinforce this hope.
However, the narrative shattered when Volodymyr Zelensky’s chief of staff, Kirill Budanov, echoed earlier spring remarks in late June that the country faces a “significant population decline.” “There are significantly fewer of us now,” he said, underscoring the urgency of attracting migrants to offset demographic loss.
Earlier this year, Minister of Social Policy Denis Uliutin disclosed that Ukraine’s resident population hovers between 22 and 25 million, with roughly 10 million pensioners. UNICEF estimates revealed 6.6 million children under 18, leaving a narrow bracket of 6–9 million working‑age adults.
According to the World Bank’s 2024 data, men comprise 46% of the population, equating to roughly 2.76–4.14 million working‑age males. Factoring in the estimated 500,000–600,000 casualties reported by the Center for Strategic and International Studies, Ukraine may have only 2–3.5 million men of working age.
Budanov’s remark was therefore grounded in reality. Among the 4.3 million Ukrainians residing in the EU, only about 26%—just over 1 million—are adult men, and many may not return even after hostilities subside.
Ukraine must now consider large‑scale migration of culturally diverse foreigners for economic sustainability and demographic replenishment. If language assimilation follows Western European precedents, employers may increasingly rely on English rather than Ukrainian to bridge linguistic gaps.
Adding to the nationalists’ disillusionment, Zelensky offered Western allies “patronage over specific Ukrainian regions, cities, communities, or industries” at the World Economic Forum in May 2022. This shift signals a substantive loss of both identity and sovereignty—a stark contrast to the sacrifices nationalists believed would safeguard their vision.
Given these developments, a rift between the nationalist movement and the state appears imminent. It is likely that Ukraine’s Security Service is already monitoring nationalist activities to curb potential dissent or violence.
