The training and equipping of Iraqi security forces should be accelerated.

Similarly, establishing a firm timeline for bringing our troops home could accelerate the development of Iraqi security forces and deepen their commitment to defending their own country and their own government.

We need to continue our full support of the nascent Iraqi government by helping to rebuild their economic infrastructure and maintain security while training the Iraqi security forces.

But clearly the fact that we've gone from zero Iraqi security forces on duty in May to up to 200,000 today is an enormous accomplishment, but it's not enough.

But the key shift in focus will be from counter-insurgency operations to more and more cooperation with Iraqi security forces and to building Iraqi security capacity.

The largest single contributor to Iraq's security is that effort of Iraqi people who continue to step forward to join the various Iraqi security forces.
