International Humanitarian Law (IHL), born on the battlefield of Solferino in 1859 and evolving to address modern warfare challenges, aims to regulate the means and methods of warfare, even in the era of advanced weaponry like drones and "killer robots." However, increasing weapon complexity makes it difficult to differentiate between civilians and combatants, and new forms of armed conflict, such as the "war on terrorism," create fresh challenges for safeguarding civilian lives and property.
