Express criticism towards the ban implemented by the government on certain countries and point out that it does not address the root problem of terrorism. Also, suggest that the ban is unfair to moderate Muslims who are trying to escape oppressive governments.
Except terrorists from Saudi Arabia can still come in and do harm.  Hmm I wonder why the brave new man in change down there didn't ban the Saudis, seeings as most Muslim terrorists attacking the US have that passport.  Seems like an obvious one to me, but no, lets ban the moderate Muslims trying to escape from the crazy Iranian govt.
