Under NATO doctrine, while any member state can commit aggressive acts of war against a nonmember, if the nonmember retaliates against the NATO member's territory, the nonmember risks war with all members of the alliance. Additionally, some nonmember states have been equipped with weapons and training to wage war as if they were member states. No provisions have ever been articulated for member states that go to war with each other. | Under NATO doctrine, while any member state can commit aggressive acts of war against a nonmember, if the nonmember retaliates against the NATO member's territory, the nonmember risks war with all members of the alliance.
