Yes, which is why turning a hospital or refugee camp into a command post is a war crime. But it also means that attacking a hospital or refugee camp, whether they’re being used as shields for military targets or not, should also not be done lightly. Iron-clad case made beforehand that it is a military target, rigorous scrutiny of the claim evaluated by an independent body after the fact, and the military action against the target has to prioritize the civilians as much as possible. They’re people. Men, women, and children who have nothing to do with the conflict and are simply caught in the crossfire. One side showing a disregard for the life of innocents does not justify the other side doubling down on the same.
