The disastrous consequences of the armed interventions against Iraq, Afghanistan, Syria, Yemen and Ukraine, to name just a few, show the urgent need to revive the principle of nonintervention into another state.

This principle of international law includes, but is not limited to, the prohibition of the threat or use of force against the territorial integrity or political independence of any state, according to Article 2.4 of the United Nations Charter.

The Swiss legal philosopher Emmerich de Vattel is credited with being the first to formulate the principle of nonintervention in his “Droit de gens ou principes de la loi naturelle” (“The Law of Nations”) published in 1758.

Essentially, the principle establishes the right of territorial sovereignty possessed by each nation. The scope of the principle, however, has been subject to debate.

For example, what constitutes intervention in practical terms? Does it include only the use or threat of military force, or does it also includes economic sanctions, cyberwarfare or other kinds of nonmilitary intervention such as propaganda campaigns or control of media messages to other countries?

According to Michael Wood, a member of the U.N. International Law Commission, one of the earliest treaty formulations of the principle was included in Article 15 (8) of the Covenant of the League of Nations and the Montevideo Convention on Rights and Duties of States of 1933, which precluded “interference with the freedom, the sovereignty or other internal affairs, or the processes of the governments of other nations,” together with the Additional Protocol on Non-Intervention of 1936.

Later on, the U.N. General Assembly issued the Declaration on the Inadmissibility of Intervention and Interference in the Domestic Affairs of States. According to Oppenheim’s International Law, the prohibition of intervention “is a corollary of every state’s right to sovereignty, territorial integrity and political independence.”

A paradigmatic case in which this principle was applied was that of Nicaragua versus United States, following the U.S. support for the “contras” fighting the Nicaraguan government and the mining of Nicaraguan harbors. The case was decided in 1986 by the International Court of Justice.

The world court ruled in favor of Nicaragua and against the U.S., and awarded reparations to the Nicaraguan government. According to the court, the actions of the U.S. against Nicaragua violated international law. The U.S. refused to participate in the proceedings after the court rejected its argument that it lacked jurisdiction to hear the case.

In a move that did no honor to the country, the U.S. later blocked the enforcement of the judgment by the U.N. Security Council, thus preventing Nicaragua from obtaining any compensation. In 1992, under the government of Violeta Chamorro, the Nicaraguan government withdrew its complaint.

According to the court’s verdict, the U.S. was “in breach of its obligations under customary international law not to use force against another state,” “not to intervene in its affairs,” “not to violate its sovereignty,” “not to interrupt peaceful maritime commerce,” and “in breach of its obligations under Article XIX of the Treaty of Friendship, Commerce and Navigation between the parties signed at Managua on Jan. 21, 1956.”

Furthermore, the world court determined that “… the laying of mines in the waters of another state without any warning or notification is not only an unlawful act but also a breach of the principles of humanitarian law underlying the Hague Convention No. VIII of 1907.”

The principle of nonintervention has obvious limits in case of grave violations of human rights. For this reason, a norm called Responsibility to Protect (R2P, or RtoP) was developed.

The origin of this norm was the international community’s failure to respond to tragedies such as the Rwandan genocide in 1994 and the Srebrenica massacre in 1995.

According to this norm, sovereignty is not an absolute right, and states forfeit aspects of their sovereignty when they fail to protect their populations from mass atrocities, crimes and human rights violations. However, to avoid abuses of this principle, any international action to curb mass crimes should have the approval of the U.N.

Although the principle of nonintervention is extremely difficult to enforce in today’s complex world, its principles should be revived again. This is particularly pertinent if one considers the tremendous loss of lives that recent interventions into other states have caused.
