Through the work of Plenums, Committees and Sub-committees, NATO PA aims at promoting an inter-parliamentary dialogue on safety and security issues while establishing strong ties between both sides of the Atlantic contributing to a shared feeling of cohesion, raising awareness about significant alliance policies and security affairs, and achieving the Alliance’s objectives.
