To not speak out when those above you are obviously doing wrong and not admitting it is an even greater crime in my eyes, if more had spoken out during ww2 then some of the German atrocities might not have happened.
Rightly or wrongly in your eyes, the President and his government are elected officials and as elected officials they are accountable to the public they serve, be they in uniform or not.
Every man, women and child should have the right to critique their Government and President and seek their atonement for their errors.
You say he isn’t a leader, well far from it, to lead it takes guts and he has them in spades full, his thoughts are with his men and those put in harms way by incompetence and ineptitude and he is fighting their corner, he has put his future on the line and his pension, so has lots to lose.
I would promote him and secure his pension, he has more sense of honour and decency than any of those above him who cower and are subservient to the wishes of someone clearly well out of his depth, without the slightest guts to tell it as it is.
