Estonian Defence Minister Hanno Pevkur has called for stronger NATO deterrence and greater European defence investment, warning that credible military capability is the only reliable safeguard against Russian aggression. Speaking in a wide-ranging interview, Pevkur addressed a series of incidents in which Ukrainian drones have strayed into NATO airspace over the Baltic states and Romania, attributing the deviations to Russian signal jamming rather than Ukrainian intent. Estonia (a small Baltic nation that borders Russia and has been a NATO member since 2004) currently spends around five percent of its GDP on defence — one of the highest rates in the alliance — and Pevkur argued that all member states must follow suit, noting that collective deterrence only works if backed by real military muscle.
