"part of the support network either through willful ignorance or" this includes all Americans who pay taxes, vote for the government, etc. Ultimately everyone shares some blame but when we see someone who's more directly responsible than ourselves, we tend to blame them and forgive ourselves. As a non-America, I see Obama voters as responsible because he told them he would attack Pakistan with drones as part of his first election campaign.
I agree that as an American who voted for those in power that I am partially responsible and would be a fair target. Living in a democracy means accepting that collectively we have chosen someone to make decisions on our behalf and even if we disagree we have chosen to operate under a set of rules that govern how we disagree and how we change things (election, etc.)
So it sounds like both of you advocate both US civilians being valid targets to kill, and also that the USA should be OK with killing foreign civilians yes?
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.
