If there was a real Superman he would not tolerate Muslim leadership in America, period. When the superhero was first created he fought against anti American enemies, and Islam is no friend for America.
I wonder if any of the writers contemplated writing a storyline about the man of Steel physically removing an usurper from the Whitehouse and rooting all the Muslim Brotherhood infiltrators and collaborators.
Probably not, as most in the comic industry are flaming PC libs. Frank Miller had actually done some work on a Batman vs. Al-Qaeda graphic novel, but that concept was scrapped. Too bad.
