See, here's your problem.

So, Chuck Hagel, appearing in front of congress, noted (reported by Huffington Post):

“I would never sign off on any decision that I did not feel was in the best interests of this country,” Mr. Hagel says during his testimony before the House Armed Services Committee Wednesday. “Nor would the President of the United States, who made the final decision with the full support of his national security team.”

But clearly this means that opinions differ on the "best interests of this country".  So, it means you may have integrity but stupidity.  It is not longer clear to may of us that what you and your president consider the best interests of this country actually are.  And that is really the crux of the issue; visions of our best interest vary.  Perhaps you and your president are not malevolent, just incompetent and misguided.  Either way, time to go.
