This is the belief that gave birth to our nation. And in the long run, advancing this belief is the only practical way to protect our citizens. When people live in freedom, they do not willingly choose leaders who pursue campaigns of terror. When people have hope in the future, they will not cede their lives to violence and extremism. So around the world, America is promoting human liberty, human rights, and human dignity. We're standing with dissidents and young democracies, providing AIDS medicine to dying patients -- to bring dying patients back to life, and sparing mothers and babies from malaria. And this great republic born alone in liberty is leading the world toward a new age when freedom belongs to all nations. (来源：英语博客 http://space.englishcn.com)
For eight years, we've also strived to expand opportunity and hope here at home. Across our country, students are rising to meet higher standards in public schools. A new Medicare prescription drug benefit is bringing peace of mind to seniors and the disabled. Every taxpayer pays lower income taxes. The addicted and suffering are finding new hope through faith-based programs. Vulnerable human life is better protected. Funding for our veterans has nearly doubled. America's air and water and lands are measurably cleaner. And the federal bench includes wise new members like Justice Sam Alito and Chief Justice John Roberts.
When challenges to our prosperity emerged, we rose to meet them. Facing the prospect of a financial collapse, we took decisive measures to safeguard our economy. These are very tough times for hardworking families, but the toll would be far worse if we had not acted. All Americans are in this together. And together, with determination and hard work, we will restore our economy to the path of growth. We will show the world once again the resilience of America's free enterprise system.
Like all who have held this office before me, I have experienced setbacks. There are things I would do differently if given the chance. Yet I've always acted with the best interests of our country in mind. I have followed my conscience and done what I thought was right. You may not agree with some of the tough decisions I have made. But I hope you can agree that I was willing to make the tough decisions.
The decades ahead will bring more hard choices for our country, and there are some guiding principles that should shape our course.
While our nation is safer than it was seven years ago, the gravest threat to our people remains another terrorist attack. Our enemies are patient, and determined to strike again. America did nothing to seek or deserve this conflict. But we have been given solemn responsibilities, and we must meet them. We must resist complacency. We must keep our resolve. And we must never let down our guard.
At the same time, we must continue to engage the world with confidence and clear purpose. In the face of threats from abroad, it can be tempting to seek comfort by turning inward. But we must reject isolationism and its companion, protectionism. Retreating behind our borders would only invite danger. In the 21st century, security and prosperity at home depend on the expansion of liberty abroad. If America does not lead the cause of freedom, that cause will not be led.
As we address these challenges -- and others we cannot foresee tonight -- America must maintain our moral clarity. I've often spoken to you about good and evil, and this has made some uncomfortable. But good and evil are present in this world, and between the two of them there can be no compromise. Murdering the innocent to advance an ideology is wrong every time, everywhere. Freeing people from oppression and despair is eternally right. This nation must continue to speak out for justice and truth. We must always be willing to act in their defense -- and to advance the cause of peace.
President Thomas Jefferson once wrote, "I like the dreams of the future better than the history of the past." As I leave the house he occupied two centuries ago, I share that optimism. America is a young country, full of vitality, constantly growing and renewing itself. And even in the toughest times, we lift our eyes to the broad horizon ahead.
I have confidence in the promise of America because I know the character of our people. This is a nation that inspires immigrants to risk everything for the dream of freedom. This is a nation where citizens show calm in times of danger, and compassion in the face of suffering. We see examples of America's character all around us. And Laura and I have invited some of them to join us in the White House this evening.
We see America's character in Dr. Tony Rehcasner, a principal who opened a new charter school from the ruins of Hurricane Katrina. We see it in Julio Medina, a former inmate who leads a faith-based program to help prisoners returning to society. We've seen it in Staff Sergeant Aubrey McDade, who charged into an ambush in Iraq and rescued three of his fellow Marines.
