The zero option seems like the only sensible option to me.
What's remarkable is not just that no one who supports a continued U.S. presence in Afghanistan at this point has managed explain what exactly they are going to accomplish, it's that American politicians aren't even trying to make that case anymore. The establishment wants to stay in Afghanistan because... um, because leaving would be bad. If we can't articulate clear goals for our military adventures, we don't have clear goals. So there's no point and we should get out.
