Genetically modifying animals to enhance their aggressiveness and use for military purposes is a complex and controversial issue, involving multiple levels of science, ethics, law, and practical applications. The following is a comprehensive analysis： --- ### **1. Scientific feasibility** -**Technological status quo**: Existing gene editing technologies (such as CRISPR) have been able to modify animal genes, but behavioral characteristics such as aggressiveness are the result of complex multi-gene regulation and are affected by multiple factors such as environment and neurodevelopment. Precise enhancement of ”aggressiveness" may require long-term research. -**Case reference**: Historically, attempts have been made to train animals for military purposes (such as the “Sonic Cat” spy program in the United States during the Cold War), but there is no successful precedent for active behavior control of genetic modification. -**Limitations**: Even if the aggressiveness is enhanced, the animal's controllability, stability and task execution ability are still in doubt. Animals may cause unpredictable behavior due to instinct or stress response. --- ### **2. Military application challenges** -**Reliability issues**: Animals are susceptible to environmental interference (such as noise, climate), and may be countered by the enemy (such as sedatives, bionic interference equipment). -**Advantages of alternative solutions**: Modern military technology is more inclined to drones, AI robots, or nano-weapons. These technologies are easier to control, mass-produced, and non-morally controversial. -**Logistics and cost**: The cost of breeding, training, and maintenance of genetically modified animals may be much higher than that of traditional weapon systems. --- ### **3. Ethical and legal issues** -**Animal rights and interests**: Artificially enhancing aggressiveness may cause animal suffering or abnormal behavior, which violates the principles of animal welfare. -**International Conventions**: The Biological Weapons Convention (BWC) expressly prohibits the development of “biological agents modified by biotechnology” as weapons, and genetically modified animals may be considered illegal. -**Ecological risks**: If modified animals escape or spread, they may destroy the ecological balance (such as the problem of invasive species). --- ### **4. Social and political influence** -**Public acceptance**: Such projects may cause strong public opinion opposition and damage the country's image. -**Limited strategic deterrence**: Genetically modified animals have limited military value and are difficult to form a strategic deterrent. On the contrary, they may be regarded as “unconventional means” and cause international condemnation. --- ###**Conclusion** Although in theory, genetic modification may enhance the aggressiveness of animals, from the point of view of scientific feasibility and practical application, its military value is extremely low, and it faces huge ethical and legal obstacles. Modern military development tends to rely more on scientific and technological equipment than biological weapons. If there are related technological breakthroughs in the future, it is highly likely that the international community will pass legislation to strictly restrict such applications.
