McCain: Please 'splain

Senator McCain, quoted in NYT article:

“That’s naïve,” Mr. McCain said at a news conference in Columbus. “The first thing that you do is you make your plans and you carry out your operations as necessary for America’s national security interests. You don’t broadcast that you are going to bomb a country that is a sovereign nation.”

Really? You don't warn and threaten ahead of time? That's a bad idea? So it would be dumb to threaten Iran, or like, maybe Iraq, if they didn't, say, hand over their theoretical WMD's? And you shouldn't threaten Afghanistan if they don't hand over Osama, right? I'm glad that we agree that president newkyular's "naive". Although I think "naive" is putting it mildly.

But then how do you explain this:

" Senator McCain then gave a ringing endorsement of the president's approach to the war in Iraq, saying the mission was necessary, achievable and noble."

So this warn first, bomb later stuff is okay? I'm confruzzled. Please explain.
