Trump delegates part of the job of being President to the military

The President is supposed to set policy. The military is supposed to follow it. Or that's the way it's supposed to work. But President Trump has decided to let the military decide our troop levels in Afghanistan, and thus at least to a degree our level of commitment there.

Yeah, I know a good leader delegates. But I still have mixed emotions about this.

On one hand, I can only praise Mr. Trump for recognizing that he has no idea what he's doing in that area and delegating the decision-making to those who do. But on the other hand, there seems to be no aspect of his job in which he does know what in the world he's doing.

If only he would do that more often! At some point, having him in the Oval Office might actually become almost harmless. But on the other hand, making policy decisions is kind of... well, you know.... what he was elected to do in the first place?

Wouldn't it just have been simpler to have simply elected somebody who was qualified to be president last November, and saved a step?
