NATO should promise overwhelming military retaliation against attacks on allied territory

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.

NATO's supreme commander warned of a decisive military response to any Russian attack on allied territory. He presented the alliance as defensive while outlining how it would obstruct and defeat an assault. The warning does not establish that Russia is preparing an imminent conventional attack.
