International law expressly prohibits the use of both chemical and biological weapons. The US has agreed to a policy of â€œno first useâ€ of chemical weapons, and a policy of â€œno useâ€ â€“ even in retaliation â€“ regarding biological weapons. Suppose, however, that the US could develop a biological weapon that would make soldiers sick for 3 to 5 days without any long-term effects. What would be the legal and moral considerations governing the use of such weapons? Explain fully your answer.
