I think that where I've gotten frustrated during the course of my presidency has never been because I was getting pushed too hard by activists to see the justness of a cause or the essence of an issue.

I don't have much patience for anyone who denies that this challenge is real.

What is important is that we make sure to work together, that we understand our strength comes from unity and not division.

All of us take offense to anyone who reaps the rewards of living in America without taking on the responsibilities of living in America. And undocumented immigrants who desperately want to embrace those responsibilities see little option but to remain in the shadows, or risk their families being torn apart.

We are not a nation that says 'don't ask, don't tell.' We are a nation that says 'out of many, we are one.'

It will take time to eradicate a cancer like Isil. And any time we take military action, there are risks involved - especially to the servicemen and women who carry out these missions. But I want the American people to understand how this effort will be different from the wars in Iraq and Afghanistan. It will not involve American combat troops fighting on foreign soil.
