You just gave an example of unsubstantiated "reporting".However, in the days since, a lot of people who had actually been at those facilities when we had access have substantiated that reporting. The satellite photography only shows what's on the surface. The actual work was being done miles below the surface.
You said "miles below the surface". Here is the temperature estimate at three miles:
"The temperature three miles underground would likely range from 212 to 302 degrees Fahrenheit (100 to 150 degrees Celsius)."
The Iranian Fordow installations were 200 to 300 feet below the surface, not "miles".
