I’ve always believed that his problem was that nobody has ever said “no” to him since his father died. That is, until he became President, and found out that although he was the head of the entire Executive branch, there were limits to even what he could do.

I am convinced that the reason he showed off this document in particular was that some general he didn’t like told him how sensitive it was and that he couldn’t disclose it, and he immediately shared it just to spite the one guy who told him “no”.
