The GE Campaign is underway!
Here’s some stepped pressure: Give Iran 30 days to do whatever it is we want them to do, and if they don’t then issue an order stopping all immigration to the U. S. from Iran.
Follow that 30 days later with an order stopping all immigration from all Muslim nations. Include Saudi Arabia.
Follow that 30 days later with an order stopping all travel to and from all Muslim nations. Add a timetable for ordering all non-U. S. citizens from Muslim nations to return to their home countries.
Watch the pressure the Muslim world puts on Iran.
Heck, he might even threaten to seize Iranian assets in the U. S. That would be dicier, I think.
