I don't think we have to announce it ... as more of them realize that their leaders are being consistantly found and taken out, the idea ..." maybe I'll just go home" will take a deeper root. It's not like these guys are wearing some uniform or carrying an ID card in any case.
The hard-case ones will pick up and head to another place they think will work for them... like the Sudan.
We'll get them, as long as we can keep the Dems from providing them sanctuary.
That's a tall order...
