“He will just secretly declare it by fiat and have his henchmen (his personal Gestapo) enforce it.”
Sounds like a facsist to me.
He’s a little bit of all the ‘ists’ rolled up into one mass of hateful Muslim anger. He used (and uses) aspects of all the ‘ists’ to get and maintain power. He will finally decide and realize that he doesn’t need the subterfuge, and he will just out-and-out consolidate (seize) control completely. Then he’s just another IDI Amin or similar.
