The President does not have power under the Constitution to unilaterally authorize a military attack in a situation that does not involve stopping an actual or imminent threat to the nation.

We all remember Abraham Lincoln as the leader who saved our Union. Founder of the Republican Party.

I was pretty realistic to people about what we could get done, and the situation we were in, and trying to tamp down expectations. If you listen to my stump speeches, if you listen to what I said at Grant Park, I kept on saying, "Look, this is not just about me, this is not going to happen in one year, or one term, or even one presidency." And we tried to layer into everything we were saying a sense of hope, but also realism.

The ideals and the values of the United States inspired the entire world. I don't think any of us can say that our standing in the world now, the way children around the world look at the United States, is the same. And part of what we need to do is to send a message to the world that we are going to invest in issues like education, we are going to invest in issues that relate to how ordinary people are able to live out their dreams. And that is something that I'm going to be committed to as president of the United States.
