2016, Statement on the Shootings in Baton Rouge (July 2016) 
Contesto: We have our divisions, and they are not new. Around-the-clock news cycles and social media sometimes amplify these divisions, and I know we’re about to enter a couple of weeks of conventions where our political rhetoric tends to be more overheated than usual. And that is why it is so important that everyone -- regardless of race or political party or profession, regardless of what organizations you are a part of -- everyone right now focus on words and actions that can unite this country rather than divide it further. We don’t need inflammatory rhetoric. We don’t need careless accusations thrown around to score political points or to advance an agenda. We need to temper our words and open our hearts -- all of us. We need what we saw in Dallas this week, as a community came together to restore order and deepen unity and understanding. We need the kind of efforts we saw this week in meetings between community leaders and police -- some of which I participated in -- where I saw people of good will pledge to work together to reduce violence throughout all of our communities. That’s what’s needed right now. And it is up to all of us to make sure we are part of the solution and not part of the problem.
                                    
Barack Obama: Frasi in inglese (pagina 16)
Barack Obama è 44º Presidente degli Stati Uniti d'America. Frasi in inglese.
                                        
                                         Remarks by the President at LBJ Presidential Library Civil Rights Summit at Lyndon B. Johnson Presidential Library in Austin, Texas on April 10, 2014. http://www.whitehouse.gov/the-press-office/2014/04/10/remarks-president-lbj-presidential-library-civil-rights-summit 
2014 
Contesto: Those of us who have had the singular privilege to hold the office of the Presidency know well that progress in this country can be hard and it can be slow, frustrating and sometimes you’re stymied. The office humbles you. You’re reminded daily that in this great democracy, you are but a relay swimmer in the currents of history, bound by decisions made by those who came before, reliant on the efforts of those who will follow to fully vindicate your vision. But the presidency also affords a unique opportunity to bend those currents -- by shaping our laws and by shaping our debates; by working within the confines of the world as it is, but also by reimagining the world as it should be.
                                    
“Now, more than ever, we must do”
                                        
                                        2013, Second Inaugural Address (January 2013) 
Contesto: Our celebration of initiative and enterprise, our insistence on hard work and personal responsibility, these are constants in our character. But we have always understood that when times change, so must we; that fidelity to our founding principles requires new responses to new challenges; that preserving our individual freedoms ultimately requires collective action. For the American people can no more meet the demands of today’s world by acting alone than American soldiers could have met the forces of fascism or communism with muskets and militias. No single person can train all the math and science teachers we’ll need to equip our children for the future, or build the roads and networks and research labs that will bring new jobs and businesses to our shores. Now, more than ever, we must do these things together, as one nation and one people.

2012 
Contesto: Now, when we came together, we knew restoring that bargain — that deal, that compact — was not going to be easy. We knew it would take more than one year or one term or maybe even one President, because we had seen what had happened in the previous decade. Jobs had moved overseas. Folks were working harder and harder, but their wages or incomes, they were staying flat, sometimes even going down. The cost of everything from health care to college was going up. And then, it all culminated in the worst economic crisis since the Great Depression — a crisis that robbed too many of our friends and our neighbors of jobs, the value of their homes, their savings. And all that pushed the American Dream even further out of reach for too many working people.
                                    
                                        
                                        2013, Cape Town University Address (June 2013) 
Contesto: We always have the opportunity to choose our better history. We can always understand that most important decision -- the decision we make when we find our common humanity in one another. That’s always available to us, that choice. [... ] it can be heard in the confident voices of young people like you. It is that spirit, that innate longing for justice and equality, for freedom and solidarity -- that’s the spirit that can light the way forward. It's in you.
                                    
                                        
                                        2016, Disabled American Veterans Convention (August 2016) 
Contesto: We need to keep improving mental health care. I’ll never forget the soldiers I met at Fort Bliss. They were proud of their service, but they were struggling with issues like post-traumatic stress. So, for veterans with PTS, we made it easier for you to qualify for the VA care that you need -- no matter when you served. We’ve increased funding for veterans mental health care by more than 75 percent -- billions more dollars. More awareness and outreach -- because we have to end any shame or stigma that comes with going and getting help.
                                    
“We know our time on this Earth is fleeting.”
                                        
                                        2012, Sandy Hook Prayer Vigil (December 2012) 
Contesto: We know our time on this Earth is fleeting. We know that we will each have our share of pleasure and pain, that even after we chase after some earthly goal, whether it’s wealth or power or fame or just simple comfort, we will, in some fashion, fall short of what we had hoped. We know that, no matter how good our intentions, we’ll all stumble sometimes in some way.
We’ll make mistakes, we’ll experience hardships and even when we’re trying to do the right thing, we know that much of our time will be spent groping through the darkness, so often unable to discern God’s heavenly plans.
There’s only one thing we can be sure of, and that is the love that we have for our children, for our families, for each other. The warmth of a small child’s embrace, that is true.
The memories we have of them, the joy that they bring, the wonder we see through their eyes, that fierce and boundless love we feel for them, a love that takes us out of ourselves and binds us to something larger, we know that’s what matters.
We know we’re always doing right when we’re taking care of them, when we’re teaching them well, when we’re showing acts of kindness. We don’t go wrong when we do that.
                                    
“Human trafficking is not a business model, it is a crime”
                                        
                                        2012, Remarks at Clinton Global Initiative (September 2012) 
Contesto: Human trafficking is not a business model, it is a crime, and we are going to stop it.
                                    
                                        
                                        2016, Howard University commencement address (May 2016) 
Contesto: Racism persists. Inequality persists. Don’t worry — I’m going to get to that. But I wanted to start, Class of 2016, by opening your eyes to the moment that you are in. If you had to choose one moment in history in which you could be born, and you didn’t know ahead of time who you were going to be — what nationality, what gender, what race, whether you’d be rich or poor, gay or straight, what faith you'd be born into — you wouldn’t choose 100 years ago. You wouldn’t choose the fifties, or the sixties, or the seventies. You’d choose right now. If you had to choose a time to be, in the words of Lorraine Hansberry, “young, gifted, and black” in America, you would choose right now.
I tell you all this because it's important to note progress. Because to deny how far we’ve come would do a disservice to the cause of justice, to the legions of foot soldiers; to not only the incredibly accomplished individuals who have already been mentioned, but your mothers and your dads, and grandparents and great grandparents, who marched and toiled and suffered and overcame to make this day possible. I tell you this not to lull you into complacency, but to spur you into action — because there’s still so much more work to do, so many more miles to travel. And America needs you to gladly, happily take up that work.
                                    
                                        
                                        2013, Remarks on Economic Mobility (December 2013) 
Contesto: So let me repeat: The combined trends of increased inequality and decreasing mobility pose a fundamental threat to the American Dream, our way of life, and what we stand for around the globe. And it is not simply a moral claim that I’m making here. There are practical consequences to rising inequality and reduced mobility. For one thing, these trends are bad for our economy. One study finds that growth is more fragile and recessions are more frequent in countries with greater inequality. And that makes sense. When families have less to spend, that means businesses have fewer customers, and households rack up greater mortgage and credit card debt; meanwhile, concentrated wealth at the top is less likely to result in the kind of broadly based consumer spending that drives our economy, and together with lax regulation, may contribute to risky speculative bubbles.
                                    
“The absence of hope can rot a society from within.”
                                        
                                        2009, Nobel Prize acceptance speech (December 2009) 
Contesto: A just peace includes not only civil and political rights — it must encompass economic security and opportunity. For true peace is not just freedom from fear, but freedom from want.
It is undoubtedly true that development rarely takes root without security; it is also true that security does not exist where human beings do not have access to enough food, or clean water, or the medicine and shelter they need to survive. It does not exist where children can't aspire to a decent education or a job that supports a family. The absence of hope can rot a society from within.
                                    
“We respect the past, but we don’t pine for the past. We don’t fear the future; we grab for it.”
                                        
                                        2015, Bloody Sunday Speech (March 2015) 
Contesto: We respect the past, but we don’t pine for the past. We don’t fear the future; we grab for it. America is not some fragile thing. We are large, in the words of Whitman, containing multitudes. We are boisterous and diverse and full of energy, perpetually young in spirit. That’s why someone like John Lewis at the ripe old age of 25 could lead a mighty march. And that’s what the young people here today and listening all across the country must take away from this day. You are America. Unconstrained by habit and convention. Unencumbered by what is, because you’re ready to seize what ought to be. For everywhere in this country, there are first steps to be taken, there’s new ground to cover, there are more bridges to be crossed. And it is you, the young and fearless at heart, the most diverse and educated generation in our history, who the nation is waiting to follow.
                                    
                                        
                                        2014, Address to European Youth (March 2014) 
Contesto: It’s not a sign of strength. Anybody can make threats. Anyone can move an army. Anyone can show off a missile. That doesn’t make you strong. It does not lead to security, or opportunity, or respect. Those things don't come through force. They have to be earned. And real strength is allowing an open and participatory democracy, where people can choose their own leaders and choose their own destiny. And real strength is allowing a vibrant society, where people can think and pray and speak their minds as they please, even if it’s against their leaders -- especially if it’s against their leaders. Real strength is allowing free and open markets that have built growing, thriving middle classes and lifted millions of people out of poverty.
                                    
                                        
                                        2009, Nobel Prize acceptance speech (December 2009) 
Contesto: In today's wars, many more civilians are killed than soldiers; the seeds of future conflict are sown, economies are wrecked, civil societies torn asunder, refugees amassed, children scarred.
I do not bring with me today a definitive solution to the problems of war. What I do know is that meeting these challenges will require the same vision, hard work, and persistence of those men and women who acted so boldly decades ago. And it will require us to think in new ways about the notions of just war and the imperatives of a just peace.
We must begin by acknowledging the hard truth: We will not eradicate violent conflict in our lifetimes. There will be times when nations — acting individually or in concert — will find the use of force not only necessary but morally justified.
I make this statement mindful of what Martin Luther King Jr. said in this same ceremony years ago: "Violence never brings permanent peace. It solves no social problem: it merely creates new and more complicated ones." As someone who stands here as a direct consequence of Dr. King's life work, I am living testimony to the moral force of non-violence. I know there's nothing weak — nothing passive — nothing naïve — in the creed and lives of Gandhi and King.
But as a head of state sworn to protect and defend my nation, I cannot be guided by their examples alone. I face the world as it is, and cannot stand idle in the face of threats to the American people. For make no mistake: Evil does exist in the world. A non-violent movement could not have halted Hitler's armies. Negotiations cannot convince al Qaeda's leaders to lay down their arms. To say that force may sometimes be necessary is not a call to cynicism — it is a recognition of history; the imperfections of man and the limits of reason.
                                    
“We will defend our people and uphold our values through strength of arms and rule of law.”
                                        
                                        2013, Second Inaugural Address (January 2013) 
Contesto: 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.

Contesto: Our democracy is not the buildings, not the monuments. It's you being willing to work to make things better and being willing to listen to each other and argue with each other and come together and knock on doors and make phone calls and treat people with respect. And that doesn't end. This is just... this is just a little pit stop. This is not a period, this is a comma in the continuing story of building America.
                                    
                                        
                                        2014, Young Southeast Asian Leaders Initiative Town Hall (April 2014) 
Contesto: And when I think back to my journey, my past, I think the most important thing for -- and maybe the most important thing for all the young people here -- is to realize that you really can have an impact on the world; you can achieve your dreams. But in order to do so, you have to focus not so much on a title or how much money you’re going to make, you have to focus more on what kind of influence and impact are you going to have on other people’s lives -- what good can you do in the world. Now, that may involve starting a business, but if you want to start a business you should be really excited about the product or the service that you’re making. It shouldn’t just be how much money I can make -- because the business people who I meet who do amazing things, like Bill Gates, who started Microsoft -- they’re usually people who are really interested in what they do and they really think that it can make a difference in people’s lives. If you want to go into government, you shouldn’t just want to be a particular government official. You should want to go into government because you think it can help educate some children, or it can help provide jobs for people who need work. So I think the most important thing for me was when I started thinking more about other people and how I could have an impact in my larger society and community, and wasn’t just thinking about myself. That’s when I think your dreams can really take off -- because if you’re only thinking about you, then your world is small; if you‘re thinking about others, then your world gets bigger.

                                        2014, Sixth State of the Union Address (January 2014) 
Contesto: Citizenship means standing up for everyone's right to vote. Last year, part of the Voting Rights Act was weakened, but conservative Republicans and liberal Democrats are working together to strengthen it. And the bipartisan commission I appointed, chaired by my campaign lawyer and Governor Romney's campaign lawyer, came together and have offered reforms so that no one has to wait more than a half hour to vote. Let's support these efforts. It should be the power of our vote, not the size of our bank account, that drives our democracy.

2012 
Contesto: There are a lot of wealthy, successful Americans who agree with me — because they want to give something back. They know they didn't — look, if you've been successful, you didn't get there on your own. You didn't get there on your own. I'm always struck by people who think, "well, it must be because I was just so smart." There are a lot of smart people out there. "It must be because I worked harder than everybody else." Let me tell you something — there are a whole bunch of hardworking people out there.If you were successful, somebody along the line gave you some help. There was a great teacher somewhere in your life. Somebody helped to create this unbelievable American system that we have that allowed you to thrive. Somebody invested in roads and bridges; if you've got a business, you didn't build that. Somebody else made that happen. The Internet didn't get invented on its own. Government research created the Internet so that all the companies could make money off the Internet.
                                    
“Now, it will take time to eradicate a cancer like ISIL.”
                                        
                                        2014, Statement on ISIL (September 2014) 
Contesto: Now, it will take time to eradicate a cancer like ISIL. And any time we take military action, there are risks involved –- especially to the servicemen and women who carry out these missions. But I want the American people to understand how this effort will be different from the wars in Iraq and Afghanistan. It will not involve American combat troops fighting on foreign soil. This counterterrorism campaign will be waged through a steady, relentless effort to take out ISIL wherever they exist, using our air power and our support for partner forces on the ground. This strategy of taking out terrorists who threaten us, while supporting partners on the front lines, is one that we have successfully pursued in Yemen and Somalia for years. And it is consistent with the approach I outlined earlier this year: to use force against anyone who threatens America’s core interests, but to mobilize partners wherever possible to address broader challenges to international order.
