<< This guy is psychotic. >>
Or -- more likely -- an Alcoholic.
O'Neill's public persona is that of a classic sufferer of that progressive, incurable, degenerative and [Unless put in remission by total abstinence] inevitably fatal disease that annually kills more Americans than the next score of diseases combined: Alcoholism.
[A physical allergy to alcohol that manifests itself in the phenomenon of craving -- And not to be confused with the consequences of defective behavior often called "addiction"]
If being a psychotic is knowing 2+2=5 and being completely comfortable with that fact -- and being a neurotic is knowing that 2+2=4 and not being able to stand it -- such is alcohol's ability to alter an Alcoholic's -- and ONLY an Alcoholic's -- perception of reality that only an Alcoholic may experience both states on an alternating basis.
Whether a daily or a binge drinker, every Alcoholic suffers an ever-increasingly-intense neurotic state until, by imbibing alcohol, he induces his own temporary effective psychosis and thereby relieves himself of the requirement that he learn to deal with reality.
Or, in other words, grows up.
O'Neill needs, before it is too late -- and he is dead from his disease, to sober up and then to grow up and learn to afford himself the dignity of the consequences of his own behavior.
After all, after you have grandiosely blamed the President and Armed-Forces Commander-In-Chief of the United States of America for what ails yah -- who is there left to blame?
You know he has a drinking problem, or you suspect it based on his behavior?
