Military alliances involving Luxembourg

The North Atlantic Treaty Organization (NATO) is an intergovernmental military alliance between 32 member states—30 in Europe and two in North America. Founded in the aftermath of World War II, NATO was established with the signing of the North Atlantic Treaty in 1949. The organization serves as a system of collective security, whereby its independent member states agree to mutual defence in response to an attack by any outside party. This is enshrined in Article 5 of the treaty, which states that an armed attack against one member shall be considered an attack against them all.
