think about this if by some snowball in hell chance Trump gets elected( I still say he will lose big at least in the electoral count) but imagine how many American muslims could be radicalized. Remember there are millions of american muslims who were born in this country and many in the military. Add the fact that Trump's rhetoric has called for barring them from entering if they are from certain countries or creating a registry.
You can't help but to believe that many of this american muslims will feel that they have no country and ill probably live in fear which would be very easy for them to become radicalized. It's a proven fact that when Trump first called for barring muslims- ISIS used his speech as propaganda for recruitment. This is another reason why a Trump presidency would be dangerous for the U.S booth domestically and internationally.
