Interesting requirement. Where does that leave a lot of other wars? Russia has been attacking Ukrainian infrastructure for a while. Ukraine has been attacking Russian oil production and ports, especially recently. I seem to recall a lot of infrastructure destroyed in the US invasion of Iraq. There have been a lot of wars since WW2 and I find it had to believe that those than involved bombing were all restricted to military targets.
A lot of war is about economics and logistics.
Edit: to add, what about Iran's threats to destroy water supplies?
