Not to worry about Iran’s buried stuff. A bunker buster on each side of each entry will seal the whole thing off for a decade or two-——and suffocate all the geniuses that are in the hole at the time——not seeing the downside here. When one hides ones stuff in a known hole -in-the-ground one sets oneself up for great disappointment. Remember how we quit building shore defense guns as soon as WW II broke out? It was obvious it was going to be an air war and fixed defenses were obsolete. Hitler kept building fixed defenses and the 8th Air Force w/ Bomber Harris ate his lunch. We did build an aircraft assembly plant underground at Wheeler AFB in Hawaii but it was not air raid safe. It was just out of sight. And we’ve even retired Cheyenne mountain as a main facility for the same kinds or reasons. If you’re not mobile you’re dead.
Found this odd image searching for a Patton image...just have to post the silly thing :-)
