Climatic weapons
This weapon, unlike the others on this list, has a rather hypothetical effect. History knows only a few examples of deliberate changes in climate and weather in a single territory. For example, during the Vietnam War, the US military thus achieved a significant lengthening of the rainy season, which led to a monstrous disruption of the natural balance and the extinction of entire populations of animals and plants. Despite the enormous financial losses caused by such an attack, it hardly brought any real military benefit. In the end, in 1987, the Convention on the Prohibition of the Hostile Use of Means of Influence on Nature entered into force and today such operations are carried out by some states exclusively for peaceful purposes.
