The International Call to Fight

After Russia launched its full-scale invasion of Ukraine in February 2022, there was relatively wide-ranging support of the call from Ukraine for foreign volunteers to join its military efforts based on nations’ perceived alliances to Ukraine, considerations of European security, and concerns over threats from Russia and its interests and allies. This brief addresses the implications and impacts of the international call to fight in Ukraine in order to gauge potential threats and to encourage preparations for the successful return and reintegration of volunteers into civilian life. It raises awareness of the societal reintegration preparations needed by the countries of origin for the mental, physical, and potentially ideological challenges these foreign volunteers may have faced while responding to the defense of Ukraine.
