Q: If you were to go back and change anything from your political career, what would it be?

A: Well, of course, the biggest disappointment for me is that we are still in this war in Iraq, and, ah, I had always thought at the time that, that, ah, people knew the truth they would not vote for this war and, I don't know what else, er, not have been supportive of this, I don't know what else we could have done, ah, but this has been the most damaging to us: loss of life, over 4,000, tens of thousands injured, many thousands of them permanently, cost in dollars, which is small compared to the loss of life and limb but the cost in dollars to the tune of trillions of dollars, the cost of reputation in the world, the cost in our military readiness, our capabi...eroding our...undermining our military capability to protect our interests wherever they are threatened, undermining our ability to fight the real war on terror which is in Afghanistan, uh, I don't know what else could have been done, ah, but I keep revisiting that every step of the way to think what could we have done to stop this President from taking us into a war on the basis of a false premise, without the proper preparation of our troops, without a plan for success, a strategy to leave, ah, that is where we have been for more than 2 years, we're there 2 years longer than we were in World War II.
