Second Cold WarThe Second Cold War, Cold War II, or the New Cold War are terms that refer to heightened geopolitical tensions in the 21st century. They have been used to describe the tense relations between the United States and China and, similarly, between the United States and Russia, the primary successor state of the former Soviet Union, which took part in the original Cold War. The terms are sometimes used to describe tensions in multilateral relations.
Nuclear arms raceThe nuclear arms race was an arms race competition for supremacy in nuclear warfare between the United States, the Soviet Union, and their respective allies during the Cold War. During this same period, in addition to the American and Soviet nuclear stockpiles, other countries developed nuclear weapons, though none engaged in warhead production on nearly the same scale as the two superpowers. The first nuclear weapon was created by the United States of America during the Second World War and was developed to be used against the Axis powers.
Arms industryThe arms industry, also known as the defence industry (or defense industry), the military industry, or the arms trade, is a global industry which manufactures and sells weapons and military technology. Public sector and private sector firms conduct research and development, engineering, production, and servicing of military material, equipment, and facilities. Customers are the armed forces of states, and civilians. An arsenal is a place where arms and ammunition – whether privately or publicly owned – are made, maintained and repaired, stored, or issued, in any combination.
Deterrence theoryDeterrence theory refers to the scholarship and practice of how threats or limited force by one party can convince another party to refrain from initiating some other course of action. The topic gained increased prominence as a military strategy during the Cold War with regard to the use of nuclear weapons and is related to but distinct from the concept of mutual assured destruction, according to which a full-scale nuclear attack on a power with second-strike capability would devastate both parties.
Security dilemmaIn international relations, the security dilemma (also referred to as the spiral model) is when the increase in one state's security (such as increasing its military strength) leads other states to fear for their own security (because they do not know if the security-increasing state intends to use its growing military for offensive purposes). Consequently, security-increasing measures can lead to tensions, escalation or conflict with one or more other parties, producing an outcome which no party truly desires; a political instance of the prisoner's dilemma.
Space RaceThe Space Race was a 20th-century competition between two Cold War rivals, the United States and the Soviet Union, to achieve superior spaceflight capability. It had its origins in the ballistic missile-based nuclear arms race between the two nations following World War II. The technological advantage demonstrated by spaceflight achievement was seen as necessary for national security, and became part of the symbolism and ideology of the time.
WarWar is an intense armed conflict between states, governments, societies, or paramilitary groups such as mercenaries, insurgents, and militias. It is generally characterized by extreme violence, destruction, and mortality, using regular or irregular military forces. Warfare refers to the common activities and characteristics of types of war, or of wars in general. Total war is warfare that is not restricted to purely legitimate military targets, and can result in massive civilian or other non-combatant suffering and casualties.
WeaponA weapon, arm or armament is any implement or device that is used to deter, threaten, inflict physical damage, harm, or kill. Weapons are used to increase the efficacy and efficiency of activities such as hunting, crime, law enforcement, self-defense, warfare, or suicide. In broader context, weapons may be construed to include anything used to gain a tactical, strategic, material or mental advantage over an adversary or enemy target.
Proxy warA proxy war is an armed conflict between two states or non-state actors, one or both of which act at the instigation or on behalf of other parties that are not directly involved in the hostilities. In order for a conflict to be considered a proxy war, there must be a direct, long-term relationship between external actors and the belligerents involved. The aforementioned relationship usually takes the form of funding, military training, arms, or other forms of material assistance which assist a belligerent party in sustaining its war effort.
Nuclear disarmamentNuclear disarmament is the act of reducing or eliminating nuclear weapons. Its end state can also be a nuclear-weapons-free world, in which nuclear weapons are completely eliminated. The term denuclearization is also used to describe the process leading to complete nuclear disarmament. Disarmament and non-proliferation treaties have been agreed upon because of the extreme danger intrinsic to nuclear war and the possession of nuclear weapons. Proponents of nuclear disarmament say that it would lessen the probability of nuclear war occurring, especially accidentally.
