This article takes a comprehensive look at developments in Latvia’s security and defence policies since 2014. The annexation of Crimea and the outbreak of the military conflict in Ukraine provided a major impetus for Latvian decision-makers to counter external and domestic threats to national security. The article discusses three key aspects of Latvia’s post-2014 security and defence developments. First, it looks at the transformation of security perceptions on the policy-making level. Second, the article discusses Latvia’s efforts to strengthen its military capabilities. Domestic security developments are also discussed. Third, differences between attitudes of Latvians and Russian-speakers towards a number of security and defence-related issues are presented. The article concludes that much has been done since 2014, but progress has been uneven. It will take more than just a few years to close the existing gaps in domestic and external security of Latvia.
