NATO Defense Expenditure Budget

The increase in the number of NATO members over the years hasn’t been sustained by an increase in the defense expenditures. Being concerned about the decreasing defense budgets and aiming to improve financial equity commitments and boost the effectiveness of financial expenditure, NATO members met at the 2014 Wales Summit to establish the Defense Investment Pledge. Members considered it necessary to contribute at least 2% of their Gross Domestic Product (

) to defense and 20% of their defense budget to major equipment which includes allocations to defense research and development by 2024. The implementation of the Defense Investment Pledge is hindered by the lack of legal binding obligation by the members, European Union fiscal laws, member states’ domestic public expenditure priorities, and political willingness. In 2021, eight member states achieved the goal of 2% GDP contribution to defense spending. In 2020, 18 NATO members were able to reach the target of 20% contribution to major equipment. The improvements in the compliance with the Wales recommendations are facilitated by the increasing risk to the security of the members posed by the Russian Federation.

Political dialogue with Japan began in 1990, and since then, the Alliance has gradually increased its contact with countries that do not form part of any of these cooperation initiatives. In 1998, NATO established a set of general guidelines that do not allow for a formal institutionalization of relations, but reflect the Allies' desire to increase cooperation. Following extensive debate, the term "Contact Countries" was agreed by the Allies in 2000. By 2012, the Alliance had broadened this group, which meets to discuss issues such as counter-piracy and technology exchange, under the names "partners across the globe" or "global partners".

(NAC) is the body which has effective governance authority and powers of decision in NATO, consisting of member states' permanent representatives or representatives at higher level (ministers of foreign affairs or defence, or heads of state or government). The NAC convenes at least once a week and takes major decisions regarding NATO's policies. The meetings of the North Atlantic Council are chaired by the secretary general and, when decisions have to be made, action is agreed upon by consensus. There is no voting or decision by majority. Each state represented at the Council table or on any of its subordinate committees retains complete sovereignty and responsibility for its own decisions. *

The NATO Parliamentary Assembly (NATO PA) is a body that sets broad strategic goals for NATO, which meets at two session per year. NATO PA interacts directly with the parliamentary structures of the national governments of the member states which appoint Permanent Members, or ambassadors to NATO. The NATO Parliamentary Assembly is made up of legislators from the member countries of the North Atlantic Alliance as well as thirteen associate members. It is however officially a structure different from NATO, and has as aim to join deputies of NATO countries in order to discuss security policies on the NATO Council.


Legal authority of NATO commanders

NATO is an alliance of 30 sovereign states and their individual sovereignty is unaffected by participation in the alliance. NATO has no parliaments, no laws, no enforcement, and no power to punish individual citizens. As a consequence of this lack of sovereignty the power and authority of a NATO commander are limited. NATO commanders cannot punish offences such as failure to obey a lawful order; dereliction of duty; or disrespect to a senior officer. NATO commanders expect obeisance but sometimes need to subordinate their desires or plans to the operators who are themselves subject to sovereign codes of conduct like the UCMJ. A case in point was the clash between General Mike Jackson (British Army officer), Sir Mike Jackson and General Wesley Clark over Incident at Pristina airport, KFOR actions at Pristina Airport. NATO commanders can issue orders to their subordinate commanders in the form of operational plans (OPLANs), operational orders (OPORDERs), tactical direction, or fragmental orders (FRAGOs) and others. The joint rules of engagement must be followed, and the Law of Armed Conflict must be obeyed at all times. Operational resources "remain under national command but have been transferred temporarily to NATO. Although these national units, through the formal process of transfer of authority, have been placed under the operational command and control of a NATO commander, they never lose their national character." Senior national representatives, like Chief of the Defence Staff (disambiguation), CDS, "are designated as so-called red-cardholders". Caveats are restrictions listed "nation by nation... that NATO Commanders... must take into account."
