Has it been even a year since ISIS announced its plan to do just that, overwhelm Europe and the US with muzzies, and use them to enact a campaign of terror? I know it was in the news for about a second, then just dropped out of the news. As evil as I believe Hussein to be, I really believe that he’d be onboard with allowing this to happen.
If he wasn't somehow actively funding and promoting it. Recall, that the MB is heavily represented in DHS and Intelligence agencies.
