We cannot fight communism all over the world, and I think we should have learned that lesson by now.

Great challenges confront our great nation. We seek to meet them by rising to the task, not by defining our country down.

It's hard to say that something is legitimate when a whole portion of the country can't vote and doesn't vote.

I defended this country as a young man, and I will defend it as president.

I saw courage both in the Vietnam War and in the struggle to stop it. I learned that patriotism includes protest, not just military service.

I'm not going to put my energy into focusing on things that are hypothetical that we don't know.

We need to put our faith and trust in the people on the frontlines -- and back it up with real resources. We need to make sure first defenders have the gear and support they need, and the benefits and protections they've earned. With new technology and ingenuity, by doing more to sustain our first defenders and calling on Americans to do more for their country, we can make our country stronger, safer, and more secure.
