The
laws of
public international law that determine whether launching a war is legally justified are called
jus ad bellum.
NATO's argument for the bombing's legitimacy NATO described the conditions in
Kosovo as posing a risk to regional stability. As such, NATO and certain governments asserted they had a legitimate interest in developments in Kosovo, due to their impact on the stability of the whole region which, they claimed, is a legitimate concern of the Organisation.
The UN Charter The
UN Charter is legally binding on all
United Nations member states, including all members of NATO, because they have each signed it. Article 2(4) of the UN Charter prohibits the use of force by UN member states to resolve disputes, but with two specific exceptions to this general prohibition: • The first exception is set forth in
Chapter VII – the
UN Security Council has the power to authorize the use of force in order to fulfill its responsibility to maintain international peace and security. In particular, Article 42 states that should the Security Council consider that measures provided for in Article 41 would be inadequate or have proved to be inadequate, it may take such action by air, sea, or land forces as may be necessary to maintain or restore international peace and security. Such action may include demonstrations, blockade, and other operations by air, sea, or land forces of Members of the United Nations. • Article 51 contains the second specific exception to the prohibition on the use of force – the right to self-defence. In particular, Article 51 states that nothing in the present charter shall impair the inherent right of individual or collective self-defence if an armed attack occurs against a Member of the United Nations, until the Security Council has taken measures necessary to maintain international peace and security. The United Nations considers NATO to be a "regional arrangement" under UN Article 52, which allows it to deal with matters relating to the maintenance of international peace and security as are appropriate for regional action provided that such arrangements or agencies and their activities are consistent with the Purposes and Principles of the United Nations. However, the UN policy on military intervention by regional arrangements in UN Article 53 states the Security Council can, where appropriate, "utilize such regional arrangements or agencies for enforcement action under its authority. However, no enforcement action shall be taken under regional arrangements or by regional agencies without the authorization of the Security Council." The arguments in favour of the legality of intervention are twofold. Articles 1(3), 55, and 56 of the UN charter impose the legal obligation on UN member states to respect basic human rights. Three prior Chapter VII UN Security Council resolutions had already concluded that Yugoslavia was in violation of these basic human right. However, the use of force is not explicitly authorised in either the two Security Council resolutions resolutions nor Articles 1(3), 55, and 56 of the UN charter. Thus proponents of the legality of the invasion argue that
international customary law authorises the use of force. Article 5 of NATO's charter calls on NATO members to respond in mutual defense when any NATO member is attacked. It is unclear whether under the NATO charter force may be used in the absence of such an attack. Article 5 has been interpreted as restricting NATO's use of force to situations where a NATO member has been attacked. It has been argued, therefore, that NATO's actions were in violation of the charter of NATO.
International criticism of NATO actions Kofi Annan UN Secretary-General Kofi Annan supported intervention in principle, saying "there are times when the use of force may be legitimate in the pursuit of peace", but was critical of unilateral action by NATO. He argued "under the [UN] Charter the Security Council has primary responsibility for maintaining international peace and security - and this is explicitly acknowledged in the North Atlantic Treaty. Therefore, the Council should be involved in any decision to resort to the use of force."
Russian attempt to end the bombing On the day the bombing started, Russia called for the
UN Security Council to meet to consider "an extremely dangerous situation caused by the unilateral military action of the North Atlantic Treaty Organization (NATO) against the Federal Republic of Yugoslavia". However, a draft resolution, tabled jointly by Russia, Belarus and India, to demand "an immediate cessation of the use of force against the Federal Republic of Yugoslavia" was defeated. Among the 15 UN Security Council nations, there were three votes in favour (Russia, China and Namibia) and twelve against, with no abstentions.
Argentina,
Bahrain,
Brazil,
Gabon,
Gambia,
Malaysia, and
Slovenia, along with the US, Britain, France, Canada, and Netherlands voted against it. Rejection of Russia's condemnation amounted to political, but not legal, support of NATO's intervention. After the war ended with the
Kumanovo Treaty and the bombing stopped, some argued that the creation on 10 June 1999 of the UN Interim Administration Mission in Kosovo (UNMIK), by Security Council Resolution 1244 (1999), constituted a legal ratification post festum (after the event).
Muammar Gaddafi One of the few countries to support the Yugoslav government fully during the NATO bombing of Yugoslavia was that of
Libya under Muammar Gaddafi. This friendship between Libya and Yugoslavia dates back to before the fall of the latter, as Gaddafi maintained a close relationship with
Josip Broz Tito. At his 2009 speech to the United Nations General Assembly, Gaddafi strongly condemned the intervention in Yugoslavia, along with earlier U.S. interventions in
Grenada and
Panama. Libya's support for Yugoslavia throughout the 1990s led to many in Serbia supporting the Gaddafi government in during the
First Libyan Civil War in 2011, with many Serbs drawing parallels between the
2011 NATO intervention in Libya and Serbia's own experience with NATO intervention. ==Humanitarian reasoning==
