I disagree. While I'd personally like a Muslim ban, that would be unconstitutional. There are better ways to deal with Muslim terrorism and Saudi Arabia is pretty good at that. While they are fundamentalist and repressive themselves, they track violent muslims and arrest them.
The more important questions are what are we going to do about the oil wealth controlled by Muslims. Trump have some answers for that like forcing them to reduce prices. How are we going to protect Israel from being nuked by Muslims? Trump has answers for that too.
What does it take for a nation to be an enemy of this country - remember 9-11 mostly Saudi - why because these crooks masquerading as royalty were buying off Bin Ladin sponsoring Palestinian Terror Groups, doing who knows what in Syria - so they can keep their pervert crime family in control of those oil fields, so they can fund more terror so they can sell more oil and on and on it goes.
Saudi Arabia and Iran are opposite sides of the same coin except Iranians actually have a culture that in the past has demonstrated a nation that has it in them not to be a shithole country
