Yes, indeed, you are...

That tweet is totally out of character.

I'm sure they are already writing up a suit to get any monies Bolton makes. Maybe that made him mellow and happy?

A libel case by Trump against Bolton will go nowhere at all, since truth is an absolute defense.

The book will be published - which means Trump lost, because even more stinking piles of his poo are being revealed. The part Bolton could still lose is the possible forfeiture of profits. This would be perfect justice, and it wouldn't benefit Trump because he won't get the money (maybe he doesn't know that).

Enjoy your precious bubble, Dotard.

This is quite typical thinking for a person with a Cluster B personality disorder. They’re inherently sadistic, and they “win” when they hurt others. They don’t need to get anything out of the conflict in order to feel that they have won. Just hurting their opponent is enough.

'Cluster B

Personality disorders—atypical ways of thinking about oneself and relating to other people—are grouped into three clusters: A, B, and C. Cluster B disorders are marked by inappropriate, volatile emotionality and often unpredictable behavior. The disorders in Cluster B are antisocial personality disorder, borderline personality disorder, histrionic personality disorder, and narcissistic personality disorder.'

This is his narcissism showing clearly.
