Cuba is actually one where I am more optimistic because of the unique nature of Cuba - 90 miles off our shore with a massive ex-patriot population, now Cuban-American population that still have deep links to the island. There I am more confident that over time that the winds of commerce and telecommunication and travel start shifting the nature of that regime. But that's a small country which has almost a unique relationship to us.

This week I've travelled more than 15,000 miles from America to China to Burma to Australia. I have no idea what time it is right now.

If we're trying to protect the American public, we should not put in place a travel ban.

Because of you, in Afghanistan we've broken the momentum of the Taliban. Because of you, we've begun a transition to the Afghans that will allow us to bring our troops home from there. And around the globe, as we draw down in Iraq, we have gone after al Qaeda so that terrorists who threaten America will have no safe haven, and Osama bin Laden will never again walk the face of this Earth.

While we have come a long way since the Stonewall riots in 1969, we still have a lot of work to do. Too often, the issue of LGBT rights is exploited by those seeking to divide us. But at its core, this issue is about who we are as Americans. It's about whether this nation is going to live up to its founding promise of equality by treating all its citizens with dignity and respect.

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.

John McCain likes to say that he'll follow bin Laden to the Gates of Hell - but he won't even go to the cave where he lives.
