Leave Fordow untouched and make a museum out if it. The islamist thugocracy in Tehran will collapse in a minute.
Even if the regime completes its inevitable collapse before we can destroy Fordow, the MOP should still be used on the facility to ensure that it will never be available in the future to hide and protect any similar program, and to send a message to the CCP and even Russia that we can reach even the most heavily reinforced sites without needing to escalate to nukes.
