Wettrüsten refers to an arms race, where countries compete to build up their military capabilities, often by increasing the quantity and quality of weapons. This competition can lead to heightened tensions and insecurity, as nations feel pressured to match or exceed the military strength of their rivals. Historically, Wettrüsten has been a significant factor in international relations, particularly during the Kalten Krieg (Cold War) between the USA and the Sowjetunion. The pursuit of advanced weaponry, including nuclear arms, created a precarious balance of power, influencing global politics and security strategies.
