Should ISIS fighters/wives/children be repatriated?

[Mister Agenda]

Here's one way rendering someone stateless can play out: The country that has them now doesn't want to claim them either, they figure it should be somebody else's problem, so they turn them loose at the border and tell them not to come back. Is that better than taking them back and holding them to account in court?

So far I'm seeing suggestions that they have 'accidents', be tried in absentia and executed upon repatriation, or hope that those who have them in custody execute them. Is there anyone else on this thread who gives the slightest shit about due process?
