And that, I suppose, is what I'd been trying to tell my mother that day: that her faith in justice and rationality was misplaced, that we couldn't ov… - Barack Obama

all the education and good intentions in the world couldn’t help plug up the holes in the universe or give you the power to change its blind, mindless course.

Then again, a president wasn’t a lawyer or an accountant or a pilot, hired to carry out some narrow, specialized task. Mobilizing public opinion, shaping working coalitions - that was the job. Whether I liked it or not, people were moved by emotion, not facts. To elicit the best rather than the worst of those emotions, to buttress those better angels of our nature with reason and sound policy, to perform while still speaking the truth - that was the bar I needed to clear.

The U.S. military has performed valiantly and brilliantly in Iraq. Our troops have done all that we have asked them to do and more. But no amount of American soldiers can solve the political differences at the heart of somebody else's civil war, nor settle the grievances in the hearts of the combatants. It is my firm belief that the responsible course of action - for the United States, for Iraq, and for our troops - is to oppose this reckless escalation and to pursue a new policy. This policy that I've laid out is consistent with what I have advocated for well over a year, with many of the recommendations of the bipartisan Iraq Study Group, and with what the American people demanded in the November election. When it comes to the war in Iraq, the time for promises and assurances, for waiting and patience, is over. Too many lives have been lost and too many billions have been spent for us to trust the President on another tried and failed policy opposed by generals and experts, Democrats and Republicans, Americans and many of the Iraqis themselves. It is time for us to fundamentally change our policy. It is time to give Iraqis their country back. And it is time to refocus America's efforts on the challenges we face at home and the wider struggle against terror yet to be won.

You know, my faith is one that admits some doubt.
