It's a bit more nuanced. It depends on who we're at war with. If it's a nation, then sure, the nation and it's support system (workers, factories, etc.) should be valid targets. For non-state sponsored actors (terrorists, etc.), it becomes a lot more muddy. For example, in Pakistan, the general population isn't actively supporting terrorism and it's not advocated by the state so they are not valid targets. However, in areas where the Taliban have control and are supported and aided by the villages, the target list should expand.

At the end of the day, my original argument was that the delineation of military vs. civilian targets allows us to ignore our roles as citizens of a nation-state at war. I also think that many conflicts get dragged out and result in a lot more pain and suffering than if we had more flexibility.
