Why would Iran bury their facilities hundreds of feet underground if they were just refining to 20%?
They are working on a bomb. Delivery could be as simple as a container ship.
Or give it to a terrorist group kookier than themselves. (if that’s possible)
As far as their concern about retaliation, it’s their ride to heaven. They are looking forward to it.
Good points, particularly about a ship delivered nuke. I have always thought they could get one within Tel Aviv.
A crude device is very heavy to transport and they don’t have the “reflectors” to get enough blast yield for a portable nuke.
No problem on a ship.
