This is something that I'm sure I'd have serious debates with my fellow Christians about. I think that the difficult thing about any religion, including Christianity, is that at some level there is a call to evangelize and prostelytize. There's the belief, certainly in some quarters, that people haven't embraced Jesus Christ as their personal savior that they're going to hell.

If you want a model for what is possible, if you want to see how to build a peaceful and prosperous and dynamic society, then look at Berlin and look at Germany.

Yes, this is hard. But there should be no question that the United States of America is stepping up to the plate. We recognize our role in creating this problem; we embrace our responsibility to combat it. We will do our part, and we will help developing nations do theirs. But we can only succeed in combating climate change if we are joined in this effort by every nation - developed and developing alike. Nobody gets a pass.

If we have a phased redeployment where we're as careful getting out as we were careless getting in, then there's not reason why we shouldn't be able to prevent the wholesale slaughter I think some people have suggested might occur.

We, the People, recognize that we have responsibilities as well as rights; that our destinies are bound together; that a freedom which only asks what's in it for me, a freedom without a commitment to others, a freedom without love or charity or duty or patriotism, is unworthy of our founding ideals, and those who died in their defense.

Iran has agreed to deepen our coordination as we work to locate Robert Levinson, missing from Iran for more than eight years. Even as we rejoice in the safe return of others, we will never forget about Bob. Each and every day our hearts are with the Levinson family, and we will not rest until their family is whole again.

When Michelle and I decided that I would run for President, it was because of a shared belief in the power of community and connection, a commitment to the idea that we are our brothers' keepers.
