Arms control is a term for international restrictions upon the development, production, stockpiling, proliferation and usage of small arms, conventional weapons, and weapons of mass destruction. Historically, arms control may apply to melee weapons before the invention of firearm. Arms control is typically exercised through the use of diplomacy which seeks to impose such limitations upon consenting participants through international treaties and agreements, although it may also comprise efforts by a nation or group of nations to enforce limitations upon a non-consenting country.
The Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or other Gases, and of Bacteriological Methods of Warfare, usually called the Geneva Protocol, is a treaty prohibiting the use of chemical and biological weapons in international armed conflicts. It was signed at Geneva on 17 June 1925 and entered into force on 8 February 1928. It was registered in League of Nations Treaty Series on 7 September 1929. The Geneva Protocol is a protocol to the Convention for the Supervision of the International Trade in Arms and Ammunition and in Implements of War signed on the same date, and followed the Hague Conventions of 1899 and 1907.
The Geneva Convention relative to the Protection of Civilian Persons in Time of War, more commonly referred to as the Fourth Geneva Convention and abbreviated as GCIV, is one of the four treaties of the Geneva Conventions. It was adopted in August 1949, and came into force in October 1950. While the first three conventions dealt with combatants, the Fourth Geneva Convention was the first to deal with humanitarian protections for civilians in a war zone. There are currently 196 countries party to the 1949 Geneva Conventions, including this and the other three treaties.
The law of war is the component of international law that regulates the conditions for initiating war and the conduct of hostilities. Laws of war define sovereignty and nationhood, states and territories, occupation, and other critical terms of law.
Legality of the Threat or Use of Nuclear Weapons[1996] ICJ 3 is a landmark international law case, where the International Court of Justice gave an advisory opinion stating that while the threat or use of nuclear weapons would generally be contrary to international humanitarian law, it cannot be concluded whether or not such a threat or use of nuclear weapons would be lawful in extreme circumstances where the very survival of a state would be at stake. The Court held that there is no source of international law that explicitly authorises or prohibits the threat or use of nuclear weapons but such threat or use must be in conformity with the UN Charter and principles of international humanitarian law. The Court also concluded that there was a general obligation to pursue nuclear disarmament.
Customary international law is an aspect of international law involving the principle of custom. Along with general principles of law and treaties, custom is considered by the International Court of Justice, jurists, the United Nations, and its member states to be among the primary sources of international law.
Protocol I is a 1977 amendment protocol to the Geneva Conventions concerning the protection of civilian victims of international war, such as "armed conflicts in which peoples are fighting against colonial domination, alien occupation or racist regimes". In practice, Additional Protocol I updated and reaffirmed the international laws of war stipulated in the Geneva Conventions of 1949 to accommodate developments of warfare since the Second World War (1937–1945).
The Hague Convention for the Protection of Cultural Property in the Event of Armed Conflict is the first international treaty that focuses exclusively on the protection of cultural property in armed conflict. It was signed at The Hague, Netherlands, on 14 May 1954 and entered into force on 7 August 1956. As of July 2021, it has been ratified by 133 states.
Military necessity, along with distinction, and proportionality, are three important principles of international humanitarian law governing the legal use of force in an armed conflict.
International law is the set of rules, norms, and standards generally recognised as binding between states. It establishes norm. Hey material scientist for states across a broad range of domains, including war and diplomacy, economic relations, and human rights. International law differs from state-based domestic legal systems in primarily, though not exclusively, applicable to states, rather than to individuals, and operates largely through consent, since there is no universally accepted authority to enforce it upon sovereign states. States may choose to not abide by international law, and even to breach a treaty but such violations, particularly of peremptory norms, can be met with disapproval by others and in some cases coercive action ranging from diplomatic and economic sanctions to war.
Distinction is a principle under international humanitarian law governing the legal use of force in an armed conflict, whereby belligerents must distinguish between combatants and protected civilians. Combatant in this instance means persons entitled to directly participate in hostilities and thus are not afforded immunity from being directly targeted in situations of armed conflict. Protected civilian in this instance means civilians who are enemy nationals or neutral citizens outside of the territory of a belligerent power.
The Martens Clause is an early international law concept first introduced into the preamble of the 1899 Hague Convention II – Laws and Customs of War on Land. There are differing interpretations of its significance on modern international law, with some scholars simply treating the clause as a reminder international customary law still applies after a treaty is ratified while others take a more expansive approach where the clause provides that because international treaties cannot be all encompassing, states cannot use that as a justification for an action.
Air warfare must comply with laws and customs of war, including international humanitarian law by protecting the victims of the conflict and refraining from attacks on protected persons.
Study of the environmental impact of war focuses on the modernization of warfare and its increasing effects on the environment. Scorched earth methods have been used for much of recorded history. However, the methods of modern warfare cause far greater devastation on the environment. The progression of warfare from chemical weapons to nuclear weapons has increasingly created stress on ecosystems and the environment. Specific examples of the environmental impact of war include World War I, World War II, the Vietnam War, the Rwandan Civil War, the Kosovo War and the Gulf War.
The Geneva Conventions are international humanitarian laws consisting of four treaties and three additional protocols that establish international legal standards for humanitarian treatment in war. The singular term Geneva Convention usually denotes the agreements of 1949, negotiated in the aftermath of the Second World War (1939–1945), which updated the terms of the two 1929 treaties and added two new conventions. The Geneva Conventions extensively define the basic rights of wartime prisoners, civilians and military personnel; establish protections for the wounded and sick; and provide protections for the civilians in and around a war-zone.
The Nuclear Terrorism Convention is a 2005 United Nations treaty designed to criminalize acts of nuclear terrorism and to promote police and judicial cooperation to prevent, investigate and punish those acts. As of October 2022, the convention has 115 signatories and 122 state parties, including the nuclear powers China, France, India, Russia, the United Kingdom, and the United States. Most recently, Zimbabwe ratified the convention on September 28, 2023.
New physical principles weapons are a wide range of weapons or systems created using emerging technologies, like wave, psychophysical, and genetic weapons.
The Luanda Agreement is a 2002 ceasefire and normalization of relations between the government of Uganda and the Democratic Republic of the Congo (DRC), signed in Luanda, Angola. It sought to end the ongoing Second Congo War and had far-reaching implications for regional peace. The Luanda Agreement became a baseline for peace accords in Africa and is viewed favorably by outside entities, such as the United Nations and the European Union.
In international humanitarian law and international criminal law, an indiscriminate attack is a military attack that fails to distinguish between legitimate military targets and protected persons. Indiscriminate attacks strike both legitimate military and protected objects alike, thus violating the principle of distinction between combatants and protected civilians. They differ from direct attacks against protected civilians and encompass cases in which the perpetrators are indifferent as to the nature of the target, cases in which the perpetrators use tactics or weapons that are inherently indiscriminate, and cases in which the attack is disproportionate, because it is likely to cause excessive protected civilian casualties and damages to protected objects.
