The President is indeed an idiot. We can agree on that.
I don't know what the acceptable level of children and innocent civilians dying is during a USA war of choice - but there certainly seems to be a lot of other sources indicating this was a tomahawk missile and that it was from the US
https://www.bbc.co.uk/news/articles/cvg548lyjnyoFrom that article:
"A senior analyst at McKenzie Intelligence Services said the munition in the video has "all the hallmarks of a US Tomahawk in its terminal phase".
"Wes Bryant, a national security analyst who served in the US Air Force, also confirmed it was a Tomahawk missile."
"An ongoing internet blackout in Iran has made it difficult to independently verify details of the incident. Restrictions on international journalists' ability to report freely in Iran makes it very hard to be sure exactly what happened in Minab on 28 February."
Article also states the clinic (target) is approximately 200m (650ft) from the school. So not at all unrealistic to think this could happen.
I also agree that the decisions on the ground operationally are not made by Hegseth ... but much like Trump and his fanboys wanted to blame Biden for the operational execution of the withdrawal from Afghanistan in 2021 which would have been planned and executed by others - Hegseth and Trump own what happens in Iran, now and for the following decades, after choosing to go to war. The Biden administration were withdrawing based on a timeline set by Trump - it was executed by those in the military and Biden was royally, and utterly vilified and crucified for what happened ... it is only possible for a true fanboy to give Trump and Hegseth a pass on what happens in Iran and all the fallout that follows.
