Why does AI ask for iron? Let's say he has no iron and wants to build swordmen. So I give him some iron and he gives me gold. Then he builds some of them but those units are now dependent on iron that doesn't belong to the AI. So if he goes to war with you, trade is canceled and all those units are now lacking the resource and suffer a penalty.
So if I am not wrong, isn't it pointless to ask another civ for strategic resources?
