PISSI organizes large and repeated atrocities against civilians in Iraq. The article calls on Westerners to "care".

I think we do care, but it is not clear what we can do to stop it. We are supporting combatants fighting against PISSI in Iraq and in Syria, but that can't be won by magic. It could be won faster by flattening cities such as Manbij and Mosul rather than trying to capture them, but that would mean a lot more civilian casualties.

Meanwhile, that victory won't immediately end bombings in Iraqi cities. Sunnis have been planting bombs against Shi'ites in Iraq since 10 years ago, long before PISSI. I don't know what anyone could do to stop it. Dubya broke things in Iraq, and the US ought to fix them; but if nobody knows how we could do so, pleas to do so are no use.
