Trump's meltdown is a perfect example of narcissistic injury, followed by narcissistic rage
The narcissistic injury factor was mentioned by Tony Schwartz, the real author of The Art of the Deal, in a tweet yesterday:

The quotes below are from the Wikipedia article "Narcissistic rage and narcissistic injury":
https://en.wikipedia.org/wiki/Narcissistic_rage_and_narcissistic_injury
Narcissistic injury occurs when a narcissist feels that their hidden, 'true self' has been revealed. This may be the case when the narcissist has a "fall from grace", such as when their hidden behaviors or motivations are revealed, or when their importance is brought into question. Narcissistic injury is a cause of distress and can lead to dysregulation of behaviors as in narcissistic rage.
Narcissistic rage occurs on a continuum from instances of aloofness, and expression of mild irritation or annoyance, to serious outbursts, including violent attacks and murder.

For Kohut, narcissistic rage is related to narcissists' need for total control of their environment, including "the need for revenge, for righting a wrong, for undoing a hurt by whatever means". It is an attempt by the narcissist to turn from a passive sense of victimization to an active role in giving pain to others, while at the same time attempting to rebuild their own (actually false) sense of self-worth. It may also involve self-protection and preservation, with rage serving to restore a sense of safety and power by destroying that which had threatened the narcissist.
Alternatively, according to Kohut, rages can be seen as a result of the shame at being faced with failure. Narcissistic rage is the uncontrollable and unexpected anger that results from a narcissistic injury – a threat to a narcissist's self-esteem or worth. Rage comes in many forms, but all pertain to the same important thing: revenge. Narcissistic rages are based on fear and will endure even after the threat is gone.
To the narcissist, the rage is directed towards the person that they feel has slighted them; to other people, the rage is incoherent and unjust. This rage impairs their cognition, therefore impairing their judgment. During the rage they are prone to shouting, fact distortion and making groundless accusations. In his book The Analysis of the Self, Kohut explains that expressions caused by a sense of things not going the expected way blossom into rages, and narcissists may even search for conflict to find a way to alleviate pain or suffering.

experts say he may not be that devastated by the loss itself. Strange, but his only ideology is himself, seeing and being seen as a great man. A giant delusion that could possibly be supported in his self-indulgent mind as much by a noisy faction perhaps following him to another TV host job as to the oval office.
It's likely that this is all costing his current brand a lot of money. Probably not many developers will want to pay to put his name on their hotels, for instance, so that's likely to be a major stressor for him, more than losing the happy fantasy of asserting his authority over "the generals."
he's got lots of others ready and willing to perpetrate the violence.
