Policy Brief

The International Call to Fight

Author : Dr. Jessica White
Date : May 2023

As part of a series of policy briefs collaboratively produced by the Global Center and the Royal United Services Institute, Dr. Jessica White addresses the implications of participation in and impacts of the fighting in Ukraine.

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.
