I would like some actual evidence of which you have provided none.He did though... What evidence do you want?
It seems evident that when even your staff officers are writing behind your back and telling your boss that your decision making is impaired there is something there. Or are you assuming that mental decline is separate from physical decline?
It;s you who are assuming about mental decline. Not me.
So what the actual evidence that the staff officers were critical of his decision making?
