It's unfortunately the case that most senior military officers tend to be those best able to ascend the greasy pole, the requirements for which are fitting in with current norms, not rocking the boat, and toadying to superiors. In consequence very few senior officers have the personality necessary to take hard decisions outside of the very narrow band they consider to be core to their personal survival as political animals. This is why the USA recently saw the disgraceful spectacle of Milley prancing like a pet ape alongside Trump as he "dominated the battlespace" last week in Washington DC.
