A revealing exchange:

During the Q&A round at the armed services committee, Senator John Warner, the Virginia Republican ... asked Petraeus a pointed question:

"Do you feel that [Iraq war] is making America safer"?

Petraeus paused before responding. He then said:

"I believe this is indeed the best course of action to achieve our objectives in Iraq."

That was, of course, a non-answer. And Warner wasn't going to let the general dodge the bullet. He repeated the question:

"Does the [Iraq war] make America safer?"

Petraeus replied, "I don't know, actually. I have not sat down and sorted in my own mind."

He's fighting a war that he hasn't even decided is vital or even beneficial to the security of the United States. That's how lost we are in mission creep. That's the depth of the hole in which Petraeus has been ordered to keep digging.
