I did. It's not something that I'm proud of. It was a mistake … But you know, I'm not going to. I never understood that line. The point was to inhale… - Barack Obama

The fact that the world’s most prosperous and successful societies, the ones with the highest living standards and the highest levels of satisfaction among their people, happen to be those which have most closely approximated the liberal, progressive ideal that we talk about and have nurtured the talents and contributions of all their citizens. The fact that authoritarian governments have been shown time and time again to breed corruption, because they’re not accountable; to repress their people; to lose touch eventually with reality; to engage in bigger and bigger lies that ultimately result in economic and political and cultural and scientific stagnation. Look at history. Look at the facts. The fact that countries which rely on rabid nationalism and xenophobia and doctrines of tribal, racial, or religious superiority as their main organizing principle, the thing that holds people together – eventually those countries find themselves consumed by civil war or external war. Check the history books. The fact that technology cannot be put back in a bottle, so we’re stuck with the fact that we now live close together and populations are going to be moving, and environmental challenges are not going to go away on their own, so that the only way to effectively address problems like climate change or mass migration or pandemic disease will be to develop systems for more international cooperation, not less.

Mandela taught us the power of action, but he also taught us the power of ideas; the importance of reason and arguments; the need to study not only those who you agree with, but also those who you don’t agree with. He understood that ideas cannot be contained by prison walls, or extinguished by a sniper’s bullet. He turned his trial into an indictment of apartheid because of his eloquence and his passion, but also because of his training as an advocate. He used decades in prison to sharpen his arguments, but also to spread his thirst for knowledge to others in the movement. And he learned the language and the customs of his oppressor so that one day he might better convey to them how their own freedom depend upon his.

I’m very proud of the United States. I believe that the United States is a force for good around the world. But I wouldn’t be a good President if I don’t listen to criticism of our policies and stay open to what other countries say about us. Sometimes I think those criticisms are unfair. Sometimes I think people like to complain about the United States because we’re doing too much. Sometimes they complain because they’re doing too little. Every problem around the world, why isn’t the United States doing something about it. Sometimes there are countries that don’t take responsibility for themselves and they want us to fix it. And then when we do try to fix it, they say why are you meddling in our affairs. Yes, it’s kind of frustrating sometimes. But the fact that we are getting these criticisms means that we’re constantly thinking, okay, is this how we should apply this policy? Are we doing the right thing when we provide aid to a country, but the country is still ruled by a small elite and maybe it’s not getting down to the people? Are we doing the right thing when we engage in training a military to become more professional, but maybe the military is still engaging in repressive activity? If we’re not open to those criticisms, then we won’t get better, we won’t improve.
