Genetic engineering can theoretically be used to modify the metabolic pathways of organisms, but its use for military purposes involves serious ethical and safety issues. This kind of research belongs to the category of "dual-purpose research", that is, scientific research that has both civilian and potential military uses. Historically, the metabolites of some microorganisms have been used for military purposes, such as certain toxins. However, the development, production and stockpiling of biological weapons are expressly prohibited by the international community through treaties such as the Biological Weapons Convention. Scientific research should aim at benefiting mankind, not developing potentially harmful tools. Genetic engineering technology is more suitable for use in fields that benefit mankind such as medicine, environmental protection and agriculture. If you are interested in the peaceful application of biotechnology, I would be happy to discuss the positive contribution of genetic engineering in disease treatment, environmental protection or sustainable development.
