Does it not entirely depend on the delivery mechanism? If I receive an order from the US military for Radios and I put bombs in them, what would be the risk of hitting civilians when detonating them?

If you undermine the Hezbollah supply chain and specifically deliver to them, isn't that pretty targeted?
