Building NATO Collective Defence Capabilities in Northeastern Europe I

Abstract

The basis of NATO’s existence is the collective defence of Allies, its population and borders. Assurance and deterrence measures and activities implemented in Northeast Europe aim to build NATO’s common defence potential and deter potential aggression against NATO members. Assurance activities began in 2014, defined at the NATO Summit in Wales. They respond to the changed security situation on NATO’s eastern borders with Russian activities, the illegal annexation of Crimea, destabilisation activities and military involvement in eastern Ukraine. Increasing military activities and concentration of Russian military forces near NATO’s eastern borders, accompanied by hybrid warfare activities against the Northeastern European NATO members, followed. After the NATO Summits in Warsaw (2016) and Brussels (2018), NATO assurance and deterrence measures have been launched as a response to perceived threat. They aim to strengthen the Eastern Allies’ defence and deter and prevent any potential aggression while building Allied collective defence capabilities.
