On April 23, 2016, President Barack Obama addressed a town-hall meeting of 500 young Leaders of the United Kingdom at London’s Lindley Hall.  Below are photographs of Obama and of some of the young leaders at the meeting.
Here is Obama’s civics lesson that is directly relevant to U.S. citizens
Post-World War II World
The U.S. and Great Britain “ultimately made up [over the American Revolutionary War] and ended up spilling blood on the battlefield together [in World War II], side-by-side, against fascism and against tyranny, for freedom and for democracy. And from the ashes of war, we led the charge to create the institutions and initiatives that sustain a prosperous peace — NATO; Bretton Woods, the Marshall Plan, the EU. The joint efforts and sacrifices of previous generations of Americans and Brits are a big part of why we’ve known decades of relative peace and prosperity in Europe, and that, in turn, has helped to spread peace and prosperity around the world.“
“And think about how extraordinary that is. For more than 1,000 years, this continent was darkened by war and violence. It was taken for granted. It was assumed that that was the fate of man. Now, that’s not to say that your generation has had it easy. Both here and in the United States, your generation has grown up at a time of breathtaking change.”
“You’ve come of age through 9/11 and 7/7 [the date of the 2005 terror attacks on a London bus and Underground trains]. You’ve had friends go off to war. You’ve seen families endure recession. The challenges of our time — economic inequality and climate change, terrorism and migration all these things are real. And in an age of instant information, where TV and Twitter can feed us a steady stream of bad news, I know that it can sometimes seem like the order that we’ve created is fragile, maybe even crumbling, maybe the center cannot hold. And we see new calls for isolationism or xenophobia. We see those who would call for rolling back the rights of people; people hunkering down in their own point of view and unwilling to engage in a democratic debate. And those impulses I think we can understand. They are reactions to changing times and uncertainty. “
“I implore you to reject those calls to pull back. I’m here to ask you to reject the notion that we’re gripped by forces that we can’t control. And I want you to take a longer and more optimistic view of history and the part that you can play in it. I ask you to embrace the view of one of my predecessors, President John F. Kennedy, who once said: “Our problems are man-made. Therefore, they can be solved by man. And man can be as big as he wants.”
The “world, for all of its travails, for all of its challenges, has never been healthier, better educated, wealthier, more tolerant, less violent, more attentive to the rights of all people than it is today. “
“That doesn’t mean we don’t have big problems. That’s not a cause for complacency, but it is a cause for optimism. You are standing in a moment where your capacity to shape this world is unmatched. What an incredible privilege that is.”
Reject “pessimism and cynicism; know that progress is possible, that our problems can be solved. Progress requires the harder path of breaking down barriers, and building bridges, and standing up for the values of tolerance and diversity that our nations have worked and sacrificed to secure and defend. Progress is not inevitable, and it requires struggle and perseverance and discipline and faith.”
“Fighting for change that you may not live to see, but that your children will live to see. That’s what this is all about. . . . Whether in the Cold War or world war, movements for economic or social justice, efforts to combat climate change — our best impulses have always been to leave a better world for the next generation.”
Abolitionists “in the 1700s . . . were fighting against slavery, and for a hundred years built a movement that eventually led to a civil war, and the amendments to our Constitution that ended slavery and called for equal protection under the law. It then took another hundred years for those rights that had been enshrined in the Constitution to actually be affirmed through the Civil Rights Act of 1964 and the Voting Rights Act of 1965. And then it’s taken another 50 years to try to make sure that those rights are realized. And they’re still not fully realized. There’s still discrimination in aspects of American life, even with a black President.”
This history means “that if any of you begin to work on an issue that you care deeply about, don’t be disappointed if a year out, things haven’t been completely solved. Don’t give up and succumb to cynicism if, after five years, poverty has not been eradicated, and prejudice is still out there somewhere, and we haven’t resolved all of the steps we need to take to reverse climate change. “
“Dr. [Martin Luther] King [,Jr.] said, ‘The arc of the moral universe is long, but it bends towards justice.’ And it doesn’t bend on its own. It bends because we pull it in that direction. But it requires a series of generations working and building off of what the previous one has done. “ (Emphasis added.)
Passion To Highlight Societal Problems
“As a general rule, I think that what, for example, Black Lives Matter is doing now to bring attention to the problem of a criminal justice system that sometimes is not treating people fairly based on race, or reacting to shootings of individuals by police officers, has been really effective in bringing attention to problems.”
Need To Have a Strategy for Change and Compromise
But “once you’ve highlighted an issue and brought it to people’s attention and shined a spotlight, and elected officials or people who are in a position to start bringing about change are ready to sit down with you, then you can’t just keep on yelling at them. And you can’t refuse to meet because that might compromise the purity of your position.”
“The value of social movements and activism is to get you at the table, get you in the room, and then to start trying to figure out how is this problem going to be solved. You, then, have a responsibility to prepare an agenda that is achievable, that can institutionalize the changes you seek, and to engage the other side, and occasionally to take half a loaf that will advance the gains that you seek, understanding that there’s going to be more work to do, but this is what is achievable at this moment.
And too often what I see is wonderful activism that highlights a problem, but then people feel so passionately and are so invested in the purity of their position that they never take that next step and say, okay, well, now I got to sit down and try to actually get something done..”
Everyone has “to be principled, you have to have a North Star, a moral compass. There should be a [good] reason for you getting involved in social issues. . . . But you have to recognize that, particularly in pluralistic societies and democratic governments like we have in the United States and the UK, there are people who disagree with us. They have different perspectives. They come from different points of view. And they’re not bad people just because they disagree with us. They may, in fact, assert that they’ve got similar principles to ours, but they just disagree with us on the means to vindicate those principles.”
Compromise “does not mean surrendering what you believe, it just means that you are recognizing the truth, the fact that these other people who disagree with you or this other political party, or this other nation — that they have dignity too, that they have worth as well, and you have to hear them and see them.”
