That actually says the opposite. That link says that Obama didnt intend to strike the hospital nor did the general and it was struck due equipment malfuntion and the info relayed to the strike crew causing it to get identified as a similar looking Taliban-controlled building. So a lower level chain of command and procedure failure. Operating in that theater and ordering those strikes was still the correct thing to do.

You can even look at the response once they realised the mistake. Trump's admin would never do anything close to that.
