Trump's Muslim ban will have exactly the opposite effect of its stated goal of "Protecting the Nation from Terrorist Attacks by Foreign Nationals". That is if one defines "nation" as a group of citizens, not just as a plot of land.

Trump has just painted targets on the backs of all of them.

ISIS should send him a "Thank You" note for the huge bump in recruitment they're about to experience.
