I believe, in the words of Dr. Martin Luther King Jr., that there is such a thing as being too late, and when it comes to climate change, that hour is almost upon us.

What is certainly true is that the American people, just like the German people, just like the British and people around the world, are seeing extraordinarily rapid change. The world is shrinking, the economies have become much more integrated and demographics are shifting.

Several Americans, unjustly detained by Iran, are finally coming home. In some cases, these Americans faced years of continued detention, and I've met with some of their families. I've seen their anguish, how they ache for their sons and husbands. I gave these families my word. I made a vow that we would do everything in our power to win the release of their loved ones, and we have been tireless.

When people are oppressed, and human rights are denied - particularly along sectarian lines or ethnic lines - when dissent is silenced, it feeds violent extremism, it creates an environment that is ripe for terrorists to exploit. When peaceful, democratic change is impossible, it feeds into the terrorist propaganda that violence is the only answer available.

Women deserve equal pay for equal work.

We live in a complex world and at a challenging time.

I think that dealing with guns is one way to handle the violent-crime issues that we have in this country.
