So many armchair quarterbacks in this thread. You haven’t defined how silly this is beyond your feelings. Are you a munition expert? If you were an AF general given this order, what tactic would you choose excluding a nuke?

  The same bomb hole tactic is an untested theory (which may be ineffective but not silly) but we’ll know more later this week once MAXAR surveillance and other independent or IAEA analysis rolls in.

You are reading the wordy "silly" incorrectly.

I'm not an expert. I just think dropping giant anvils from the sky is Loony Toons tactics. Maybe it works great! I don't know! But it's worth knowing how these things work, and how they work is: they're just super super heavy.
