By this measure, he is in contention to become the most successful pathological narcissist in history. Which is his sole goal.
I don't like it, but all the time I spent writing this comment contributes to his brain-minute score. So does the time you spend reading it.
In theory, this perspective is similar to the advice to ignore the bully. In practice, we've let this one go on too long.
He's just a narcissistic guy who wants to achieve some goals thw US had previously to show he's the only one who could do it, and to show what this great power can do (Iran, Venezuela, etc...)
I also think he's probably aware of his age and cognitive decline, so that's why he's in such a hurry to do everything as fast as possible. He's not the same as in 2017
