I do not believe that a counterterrorism strategy all by itself, without a sufficient level of counterinsurgency, will work.

The person who takes the oath of office in the next four months will shape not just the next four years, but the next forty years of our nation. In these next four years, we need proven leadership, proven judgment and proven values. America needs four more years of President Barack Obama.

I saw the president make the tough calls in the Situation Room - and today, our troops in Iraq have finally come home so America can do some nation building here at home. That was the change that we believed in. That was the change we fought for. That was the change President Obama delivered.

No officer should be allowed to behave as if they are above the law, just because they are responsible for upholding the law.
