I was watching Donald Trump interviewed by Chris Wallace on Fox News Sunday, and he again insisted that his ban on Muslims would only be temporary, until we "figure out" why some Muslims hate us so much.  He has even said he wants to enlist the help of Muslims to "figure it out."

This has always struck me as odd, as the answer seems so obvious.  There is a part of Islam that teaches that those of other religions need to be conquered, subordinated, and/or killed.  An even larger number of Muslims want to impose repressive sharia law on the world than believe in following the scriptural teachings on violent jihad.  This subset has millions of members.  We can't read minds and know which Muslims are members of the killing group and which are members of the non-killing group.  That's why we can't afford to let any more in.

Does Trump really not know this?  Let's consider all the possibilities:

1) Perhaps Trump really does not know this.  Perhaps he has never considered the source of radical Islam and really needs to be educated to know what causes it.  Perhaps, absent this knowledge, he views this as a problem to be solved as long as we have experts looking into this.  Perhaps he think there is some sort of psychological test that can be given to screen out the fanatics from the others.

2) Perhaps Trump really does know the truth, in which case he is fully aware that it is an insolvable problem as long as millions of Muslims are taught to hate us.  In which case there is no solution now, and Trump's "temporary" ban is really only meant to be temporary until madrassas stop teaching their students to kill Christians.  Which might take a few hundred years.

I tend to think that Trump does know the real truth, and that even he is afraid to call for a permanent ban.  I know Ted Cruz has called for a ban of immigrants from countries where ISIS is active, and while a good measure, it is not enough.  Canada is admitting thousands of Syrian refugees; what if one wants to cross over from Canada?  France and Germany have millions of Muslims, some of whom are radicalized.  What if some of them want to enter?

Until the global nature of Islam changes, I don't see how a ban can be temporary.  What do you think?  Is Trump simply uninformed, or is he afraid to call for what he really knows is required?
