I'd love to know how (precisely) closing visa access to nations that don't send terrorists to the US (Iran) but not to that those that do, but which happen to make scads of $$ for Trump's business pals (Saudi Arabia), makes America safer than your nation. Try suggesting this policy (visas up the wazoo for oil-rich Wahhabis) to your elected reps. It's a useful test: if they go for it, you know they're either thick or on the take.
