Not an effective line of reasoning
I didn’t know you could get a hotline to the Taliban:
Amnesty International said it appealed for the release of 21 South Korea hostages during a phone conversation with the Taliban, warning the militants that holding and killing captives was a war crime.
That’s like warning a carjacker not to rob a bank because he might go to jail. Maybe Amnesty International hasn’t noticed, but the Taliban is already a pariah and has already committed war crimes. The Taliban will give up the hostages when it figures out there’s nothing to gain.
