[T]o all who serve or have served, it has been the honor of my lifetime to be your Commander-in-Chief. And we all owe you a deep debt of gratitude. B… - Barack Obama

My fellow Americans, I know that at a time of upheaval overseas -- when the news is filled with conflict and change -- it can be tempting to turn away from the world. And as I’ve said before, our strength abroad is anchored in our strength here at home. That must always be our North Star -- the ability of our people to reach their potential, to make wise choices with our resources, to enlarge the prosperity that serves as a wellspring for our power, and to live the values that we hold so dear.

Change is hard –- in our own lives, and in the lives of nations. And change is even harder when we carry the heavy weight of history on our shoulders. But today we are making these changes because it is the right thing to do. Today, America chooses to cut loose the shackles of the past so as to reach for a better future –- for the Cuban people, for the American people, for our entire hemisphere, and for the world.

I have to also say that Africa’s democratic progress is also at risk when leaders refuse to step aside when their terms end. […] When a leader tries to change the rules in the middle of the game just to stay in office, it risks instability and strife -- as we’ve seen in Burundi. And this is often just a first step down a perilous path. And sometimes you’ll hear leaders say, well, I'm the only person who can hold this nation together. If that's true, then that leader has failed to truly build their nation. […] Nobody should be president for life. And your country is better off if you have new blood and new ideas. I'm still a pretty young man, but I know that somebody with new energy and new insights will be good for my country. It will be good for yours, too, in some cases.
