But here is the stark reality: there is a security gap in this country – a gap between the rhetoric of those who claim to be tough on national security, and the reality of growing insecurity caused by their decisions.

The way to win a debate with John McCain is not to talk, and act, and vote like him on national security, because then we all lose.

What he and the Administration have failed to present is an overarching strategy: how the war in Iraq enhances our long-term security, or will in the future.

that is why Senator McCain can argue – as he did last year – that we couldn't leave Iraq because violence was up, and then argue this year that we can't leave Iraq because violence is down.

I will set a new goal on Day One: I will end this war. Not because politics compels it. Not because our troops cannot bear the burden– as heavy as it is. But because it is the right thing to do for our national security, and it will ultimately make us safer.
