In which I agree with Dick Cheney…

…sort of. I mean, he's not entirely wrong here...

“In my mind, the foremost obligation we had from a moral or an ethical standpoint was to the oath of office we took when we were sworn in, on January 20 of 2001, to protect and defend against all enemies foreign and domestic. And that’s what we’ve done,” he said.

Upholding the oath of office is no doubt the foremost obligation of an elected official. It's hard to do, though, when you don't know what's in it. Again, the oracle...

Article II, Section 1.

...Before he enter on the execution of his office, he shall take the following oath or affirmation:--"I do solemnly swear (or affirm) that I will faithfully execute the office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States."

Nothing about enemies in there, regardless of origin, but there's a pretty clear target for protection. Not American territory, or property, or even lives. They're there to "preserve, protect and defend the Constitution of the United States.

And on that score?

Fail. Major Fail.
