“Our government has a responsibility to defend our borders, but we must do so in a way that makes us safer and upholds all that is decent and exceptional about our nation.”

Day of Affirmation Address (1966)
Context: The help and the leadership of South Africa or of the United States cannot be accepted if we, within our own country or in our relationships with others, deny individual integrity, human dignity, and the common humanity of man. If we would lead outside our borders, if we would help those who need our assistance, if we would meet our responsibilities to mankind, we must first, all of us, demolish the borders which history has erected between men within our own nations — barriers of race and religion, social class and ignorance.
Our answer is the world's hope; it is to rely on youth. The cruelties and the obstacles of this swiftly changing planet will not yield to obsolete dogmas and outworn slogans. It cannot be moved by those who cling to a present which is already dying, who prefer the illusion of security to the excitement and danger which comes with even the most peaceful progress. This world demands the qualities of youth: not a time of life but a state of mind, a temper of the will, a quality of the imagination, a predominance of courage over timidity, of the appetite for adventure over the love of ease.

2015, Address to the People of India (January 2015)
Context: Our nations are strongest when we uphold the equality of all our people -- and that includes our women. Now, you may have noticed, I’m married to a very strong and talented woman. Michelle is not afraid to speak her mind, or tell me when I’m wrong -- which happens frequently. And we have two beautiful daughters, so I’m surrounded by smart, strong women. And in raising our girls, we’ve tried to instill in them basic values -- a sense of compassion for others, and respect for themselves, and the confidence that they can go as far as their imaginations and abilities will carry them. [... ] We know from experience that nations are more successful when their women are successful. When girls go to school -- this is one of the most direct measures of whether a nation is going to develop effectively is how it treats its women. When a girl goes to school, it doesn’t just open up her young mind, it benefits all of us -- because maybe someday she’ll start her own business, or invent a new technology, or cure a disease. And when women are able to work, families are healthier, and communities are wealthier, and entire countries are more prosperous. And when young women are educated, then their children are going to be well educated and have more opportunity. So if nations really want to succeed in today’s global economy, they can’t simply ignore the talents of half their people. And as husbands and fathers and brothers, we have to step up -- because every girl’s life matters. Every daughter deserves the same chance as our sons. Every woman should be able to go about her day -- to walk the streets or ride the bus -- and be safe, and be treated with respect and dignity. She deserves that.

2013, Second Inaugural Address (January 2013)
Context: We will defend our people and uphold our values through strength of arms and rule of law.  We will show the courage to try and resolve our differences with other nations peacefully –- not because we are naïve about the dangers we face, but because engagement can more durably lift suspicion and fear. America will remain the anchor of strong alliances in every corner of the globe.  And we will renew those institutions that extend our capacity to manage crisis abroad, for no one has a greater stake in a peaceful world than its most powerful nation. We will support democracy from Asia to Africa, from the Americas to the Middle East, because our interests and our conscience compel us to act on behalf of those who long for freedom.  And we must be a source of hope to the poor, the sick, the marginalized, the victims of prejudice –- not out of mere charity, but because peace in our time requires the constant advance of those principles that our common creed describes: tolerance and opportunity, human dignity and justice.

2015, State of the Union Address (January 2015)
Context: When we make rash decisions, reacting to the headlines instead of using our heads; when the first response to a challenge is to send in our military -- then we risk getting drawn into unnecessary conflicts, and neglect the broader strategy we need for a safer, more prosperous world. That’s what our enemies want us to do. I believe in a smarter kind of American leadership. We lead best when we combine military power with strong diplomacy; when we leverage our power with coalition building; when we don’t let our fears blind us to the opportunities that this new century presents. That’s exactly what we’re doing right now. And around the globe, it is making a difference. [... ] That’s how America leads -- not with bluster, but with persistent, steady resolve.
