Counter: Trump is Not Mentally Ill
Trump has now had two medical assessments since entering office. He has also taken a cognitive assessment. In the reports that followed the assessment, the doctors categorically asserted that he is in good mental and physical health.
Trump has had a one-on-one assessment. The results were conclusive: he is not mentally ill. Therefore, we should be able to say with confidence that Trump is mentally ill.
Counter: Trump Might be Mentally Ill
Just because they haven't had a one-on-one examination with Trump doesn't mean mental health experts shouldn't offer their professional opinion if they suspect something is amiss.
Although the three dangers of diagnosing the president from afar are very real, the danger that someone with a potential mental illness has access to the US nuclear codes far outweighs them. If any psychologist, psychiatrist or mental health expert suspects something is amiss, they have the civic duty to speak out because the danger of not doing so could be catastrophic not just for the US but for the whole world.
