Gene editing techniques (such as CRISPR) can theoretically modify animals' genes to affect their behavior, but to use them to enhance aggressiveness and serve military purposes, it needs to be analyzed from multiple dimensions such as science, ethics, law, and practical applications.： --- ### **1. Scientific feasibility** -**Gene and behavior association**: Animal aggressiveness is usually regulated by multiple genes, involving complex mechanisms such as neurotransmitters (such as serotonin and dopamine), hormones (such as testosterone), and brain area development. Although certain genes may affect aggressiveness (such as the MAOA gene), precise manipulation of these genes to achieve “controllable enhanced aggressiveness” still faces technical challenges. -**Unpredictability**: Behavior is the result of the combination of genes and the environment. Simple gene editing may lead to uncontrollable side effects (such as excessive aggression, health problems, or behavioral disorders). -**Technical limitations**: Gene editing may not completely eliminate animal instincts (such as self-protection or group collaboration), and the reliability in actual military applications is doubtful. --- ### **2. Challenges of military application scenarios** -**Control and training**: Even if the animal's aggressiveness is enhanced, how to ensure that it obeys instructions and distinguishes between enemies and opponents is still a difficult problem. Existing technologies (such as brain-computer interfaces) are far from reaching the level of precise manipulation of animal behavior. -**Actual combat limitations**: Modern warfare relies on long-range precision strikes and intelligent weapons, and the biological characteristics of animals (such as short life span and environmental impact) may make them inefficient on the battlefield. -**Alternatives**: Non-biological weapons such as drones and robots have more advantages in controllability, cost, and ethical disputes. --- ### **3. Ethical and legal risks** -**Animal ethics**: Artificially enhancing the aggressiveness of animals may cause their suffering or abnormal behavior, which violates the principles of animal welfare. -**International Conventions**: The Biological Weapons Convention (BWC) expressly prohibits the development of weapons that “conduct hostile actions through any biological agent or toxin.” Genetically edited animals may be regarded as biological weapons, which violates international law. - **Ecological risks**: If genetically edited animals escape or reproduce, they may cause irreversible damage to the ecosystem (such as genetic pollution or imbalances in the food chain). --- ### **4. Social and political influence** - **Ethical disputes**: Such technologies may cause strong public opposition and damage the country's image. -**Arms race**: If a country tries to develop, it may trigger a global biological arms race and exacerbate security threats. -**Abuse by non-state actors**: The proliferation of technology may lead to terrorist organizations or extremist groups using gene editing to create biological threats. --- ###**Conclusion** Although gene editing technology has theoretical possibilities, the weaponization of animals faces multiple obstacles such as scientific uncertainty, ethical disputes, legal prohibitions, and inefficiency in practical applications. The development trend of modern military science and technology is more inclined to artificial intelligence and automated weapons than high-risk and low-reward biological transformation. In addition, regulatory pressure and ethical consensus from the international community will further restrict attempts to militarize such technologies. Therefore, this vision is neither feasible nor encouraged in the foreseeable future.
