I would hazard a guess that, firstly, we need to have the right laws in place, with courts that understand and respect their plain meaning. And secondly, we need prosecutors who are focused on these cases. Once that is all in place, the Mullahs will have to be somewhat subtle in their recruiting efforts.
The issue for me is not their recruiting, it is the blatant political and militant activism within a county providing them sanctuary. Surely they immediately fail the criteria for entry to the country? immediate deportation should follow.
