Regarding the attacks on Iran, it is unlikely they caused much harm. The program can probably be restarted in a few months. That was the conclusion of the DIA intelligence report that was leaked. The administration denigrated the report but did not deny that it came from the government. As I understand, it is unlikely there was serious damage because:

1. According to NHK (Japanese National TV) no radioactive debris was detected around the sites after the attack. Nothing was released from underground.

2. Before the attack, satellite photos showed around 40 trucks lined up at the sites. They were gone during the attack. Iran has ~8,000 kg of uranium. A large truck can carry 4,500 kg. Assuming these trucks were small, it would still only take 5 or 10 to carry the uranium, so the others probably carried machinery and instruments.

3. The sites were farther underground than the U.S. MOP bombs can reach. That is what various sources said, including Mark Hertling in the Bulwark article today (thebulwark.com/p/first-…).
