It's actually the first foreign-relations issue for the new Iraqi government. If Iran wants them to intervene in the matter, they're going to have to recognize them. No recognition, no deal.
I would personally like to see them offered land in exchange for a cessation of terrorist activities, yes, even against Iran, for whose current government I have no love at all. They want to move their activities back into Iran they need to do so without our help. Given that their families are in Iraq I'd hope for them to settle in for the wait, but it will be lonely and very uncomfortable for Shi'ite Persians in the land of the Arabs and Kurds.
I like your solution. Handing them over to the new Iraqi government is a great idea.
Great idea.
However this new government will not be in place for two to three years. In the meantime what do you do with them?
They are disarmed and cooperating (but really had no choice). We want Iran to fall sooner or latter. I suppose we try to keep them where they are going until a new government can decide. It just spreads out our troups more.
This really is a can of worms. Thankfully they have oil to pay for some of the trouble of helping them.
Kurds Sunis Shiates Baaths and these guys and who knows who else. What a problem to organise these opposing groups into a Government.
Maybe Iran will fall before then and they can go back home.
