This Info Flash aims to shed light on the case of Latvia, which passed a law in April 2023 calling for the mandatory reintroduction of military conscription after it was abolished in 2007. A perspective on the possible downfalls of such defence policy is analysed, while also contextualising the growing support for mandatory military service across the EU in the 21st century. A brief historical analysis also portrays the main reasons why it was abandoned by most European countries over the course of the last two decades and how the Russian invasion of Ukraine has generated a U-turn in defence policy in the Latvian case.
