On February 24, 2022, when the Russian Federation launched a full-scale invasion of Ukraine, the Baltic States - Lithuania, Latvia, and Estonia - were among the first to respond to the request for military and humanitarian assistance. According to the Ukraine Support Tracker, between January 24, 2022, and January 15, 2023, they were among the largest providers of military aid to Ukraine relative to their GDP – Estonia - 1.469%, Latvia - 1.128%, and Lithuania - 1.145% (Trebesch et al., 2023). One of the most important motivating factors could be the common historical past connecting the countries: the states were all part of the Soviet Union, and later, they secured their independence (Simpson, 2023). Therefore, the population of these countries, understanding the price of freedom, strives to support Ukraine on the way to its victory comprehensively. The historical experience of the Baltic States, which were under occupation until the collapse of the USSR, and the ongoing war in Ukraine have significantly influenced the perception of their security and the possible threat from Russia today. For instance, understanding the security challenges connected with the war in Ukraine, in 2023, the Latvian government adopted a law on compulsory military service, which had been abolished in 2006. This law restores mandatory military service for men and voluntary military service for women from January 1, 2024 (Fremer, 2023). Moreover, in 2024, the Baltic States and Poland called on the EU to build a defence line on the border with Russia and Belarus to prevent possible military and hybrid threats (Brzozowski, 2024).
