What the cynics fail to understand is that the ground has shifted beneath them - that the stale political arguments that have consumed us for so long no longer apply. The question we ask today is not whether our government is too big or too small，but whether it works - whether it helps families find jobs at a decent wage，care they can afford，a retirement that is dignified. Where the answer is yes，we intend to move forward. Where the answer is no，programs will end. And those of us who manage the public’s dollars will be held to account - to spend wisely，reform bad habits，and do our business in the light of day - because only then can we restore the vital trust between a people and their government.
Nor is the question before us whether the market is a force for good or ill. Its power to generate wealth and expand freedom is unmatched，but this crisis has reminded us that without a watchful eye，the market can spin out of control- and that a nation cannot prosper long when it favors only the prosperous. The success of our economy has always depended not just on the size of our Gross Domestic Product，but on the reach of our prosperity；on our ability to extend opportunity to every willing heart - not out of charity，but because it is the surest route to our common good.
As for our common defense，we reject as false the choice between our safety and our ideals. Our Founding Fathers，faced with perils we can scarcely imagine，drafted a charter to assure the rule of law and the rights of man，a charter expanded by the blood of generations. Those ideals still light the world，and we will not give them up for expedience’s sake. And so to all other people and governments who are watching today，from the grandest capitals to the small village where my father was born： know that America is a friend of each nation and every man，woman，and child who seeks a future of peace and dignity，and that we are ready to lead once more.
Recall that earlier generations faced down fascism not just with missiles and tanks，but with sturdy alliances and enduring convictions. They understood that our power alone cannot protect us，nor does it entitle us to do as we please. Instead，they knew that our power grows through its prudent use；our security emanates from the justness of our cause，the force of our example，the tempering qualities of humility and restraint.
We are the keepers of this legacy. Guided by these principles once more，we can meet those new threats that demand even greater effort - even greater cooperation and understanding between nations. We will begin to responsibly leave Iraq to its people，and forge a hard-earned peace in Afghanistan. With old friends and former foes，we will work tirelessly to lessen the nuclear threat，and roll back the specter of a warming planet. We will not apologize for our way of life，nor will we waver in its defense，and for those who seek to advance their aims by inducing terror and slaughtering innocents，we say to you now that our spirit is stronger and cannot be broken；you cannot outlast us，and we will defeat you.
For we know that our patchwork heritage is a strength，not a weakness. We are a nation of Christians and Muslims，Jews and Hindus - and non-believers. We are shaped by every language and culture，drawn from every end of this Earth；and because we have tasted the bitter swill of civil war and segregation，and emerged from that dark chapter stronger and more united，we cannot help but believe that the old hatreds shall someday pass；that the lines of tribe shall soon dissolve；that as the world grows smaller，our common humanity shall reveal itself；and that America must play its role in ushering in a new era of peace...
As we consider the road that unfolds before us，we remember with humble gratitude those brave Americans who，at this very hour，patrol far-off deserts and distant mountains. They have something to tell us today，just as the fallen heroes who lie in Arlington whisper through the ages. We honor them not only because they are guardians of our liberty，but because they embody the spirit of service；a willingness to find meaning in something greater than themselves. And yet，at this moment - a moment that will define a generation - it is precisely this spirit that must inhabit us all.
For as much as government can do and must do，it is ultimately the faith and determination of the American people upon which this nation relies. It is the kindness to take in a stranger when the levees break，the selflessness of workers who would rather cut their hours than see a friend lose their job which sees us through our darkest hours. It is the firefighter’s courage to storm a stairway filled with smoke，but also a parent’s willingness to nurture a child，that finally decides our fate.
Our challenges may be new. The instruments with which we meet them may be new. But those values upon which our success depends - hard work and honesty，courage and fair play，tolerance and curiosity，loyalty and patriotism - these things are old. These things are true. They have been the quiet force of progress throughout our history. What is demanded then is a return to these truths. What is required of us now is a new era of responsibility- a recognition，on the part of every American，that we have duties to ourselves，our nation，and the world，duties that we do not grudgingly accept but rather seize gladly，firm in the knowledge that there is nothing so satisfying to the spirit，so defining of our character，than giving our all to a difficult task.
