There's so much error being displayed here I barely know where to begin.
> Civilians dying is bad and we should avoid it, but it’s obviously not morally dispositive since we do it too.
Of course the killing of civilians is "morally dispositive." If civilians were accidentally killed in the strike our military will exhibit some accountability, and if civilians were deliberately targeted it would be a crime and it would be prosecuted.
When the Taliban kills civilians, that's the point. The civilians are the target.
Civilian deaths are an outrage but there's no moral equivalence between the parties or their actions.
> If a foreign power occupied America, Americans would do the exact same thing. In fact, that’s what Americans did during the Revolution. You can’t hope to make sense of the issue unless you morally analyze the ends for which people are fighting. Islamic State is wrong and must be stamped out because the end for which they’re fighting is wrong. Americans fighting the British to establish a Republic, by contrast, is right.
We aren't talking about the Islamic State, we're talking about the Taliban.
This just scratches the surface of how badly you misunderstand the conflict. There are a number of parties involved in the conflict in Afghanistan - including the Taliban and IS - and some of them are our allies. It is literally nothing like Americans fighting the revolution.
(in that bizarre analogy, we would be... France?)
