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.
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.
