I’ll bet you a dollar that the reason His Majesty doesn’t attend these briefings is because he doesn’t like hearing advice from people he perceives as underlings. It’s clear to me that Obama is extremely proud & haughty, and thinks he already knows whatever he needs to know. The experience of having people square off to him in the briefings and say, “You know, Mr. President, we really need to address this particular issue...” must really be the sand in his grits! So he avoids it by getting the written briefings instead ... which of course are not nearly so useful.
I'd be willing to bet it's because he can't handle the truth... especially coming from people who have seen more, faced more danger, and accomplished more before they were 30 years old than he could possibly dream of.
He doesn't see those kind of people as underlings. He fears them! He knows they are the Alpha dogs, and he knows damn well he's a Beta. They make him pee on the floor.
