I have a relative (through marriage into the family) who left Iran in the late 70s so I understand a fair amount about Iran, and yes, there is a chance than men with guns are going round giving people out to be human shields. If Trump does what he says he’ll do then they risk death and maiming whatever. .
There are plenty of cruel regimes and dictatorships. Out of interest, you are so concerned about regimes that suppress women and treat them appallingly, (and some men too!) surely you believe that the US should be invading Afghanistan (again!). Read anything by Khaled Hosseni!
And if you want to see what might happen to the US under Herr Trump and the U.K. under Herr Farage then read The Handmaids tale - although from your user name, I suspect quasi religious fervour is your thing, under the guise of being a ‘good Christian’.
