NATO members should pool control of regional drone-defence systems rather than operate separate national networks

Security arrangement under which states commit to treat an attack on one as an attack on all, obliging joint response. Underpins alliances such as NATO and provisions of the UN Charter, making shared deterrence and coordinated military planning central instruments of international stability.

Bulgaria's defence minister said the country expected to join a NATO anti-drone initiative by 30 October following attacks on nearby commercial shipping. The announcement concerned planned participation and stronger regional protection; it did not establish completed membership or the deployment of additional systems. Bulgaria's prime minister said Russian responsibility for the attacks was likely but unproven.
