That podcast episode was so annoying to listen to. John just whined about how people criticized him for saying "dropped," as though that was the only point of criticism and not, for example, his easily disproven assertion that "a rock" would be as powerful as "hundreds" of nuclear bombs. The fact that he still insists on phrasing it like "dropping rocks into Earth's gravity well" shows that he hasn't learned anything, even after he himself explains the monumental effort that it would take to actually launch a rock from the moon and get it to strike Earth compared to "dropping bombs" from the air on Earth.
By the way, this whole thing encouraged me to look up how far away the moon is from Earth: it's 239,000 miles away, compared to about 240 miles for the International Space Station. That he insists that the moon is "tactically valuable" for warfare against targets on Earth really doesn't convince me that he doesn't think that the moon is literally just a big rock hanging out in the sky. If you wanted to mess with Earth's communication satellites, going to a remote location in space doesn't seem like the optimal strategy compared to, say, cyberwarfare from the planet's surface.
