This is really bad!!
Think of all the threats they will now make to the Western world!/s
There will be no effective pressure on Iran until we interdict what they sell, now what they buy. These companies will just sell though third parties like everyone else is doing.
They have had 50+ years of oil income, and complete access to the finest western technical universities to train their own engineers.
Yet they remain dependent on the west.
They're not needed any more.
Iran has nukes for power AND warfare.
Iran thanks all involved for coming over and teaching them everything they know and are now self sufficient.
They will NOT be a post WW2 Japan.
