Happy Purim to all.
It seems to me that despite all the endless talk about Iranian sanctions, there are 2 modalities if used that would bring the regime to its knees.
1-= remove all the insurance on world cargo ships that carry material to Iran.No shipping company would allow its ships to operate without insurance.This can be done by governmental pressure on maritime insurance companies.
2-=stop the sale of gasoline to Iran. They have much oil,however only 2 factories to produce gasoline.
Both steps would lead to an uprising,and could bring the regime to its knees.
