Secretary of Defense Hegseth has been firing top military people based on whether he thinks their politics align with his. And, he is firing well respected people with great experience.
The first day of the war the US slaughtered Iranian girls in a girls school. This was hopefully a legitimate mistake, but, the US has the obligation to acknowledge what happened and explain it to the public. Instead, Hegseth and Trump refuse to talk about it.
Hegseth may have done his job well when he was in the military, but he did not have the experience to be Secretary of Defense. He also doesn’t have the personality to be Secretary of Defense. He had problems with alcohol, with his own finances, and regularly publicly spoke like a biased reactionary partisan hack who buys into many falsehoods and exaggerations often told by Trump and his supporters.
