I have spoken to all of them who are living. I didn't want to get into a Nancy Reagan thing about doing any séances. - Barack Obama

Precisely because we are willing to bear its burden, we know well the cost of war. And that is why we built an alliance that was strong enough to defend this continent while deterring our enemies. At its core, NATO is rooted in the simple concept of Article Five: that no NATO nation will have to fend on its own; that allies will stand by one another, always. And for six decades, NATO has been the most successful alliance in human history.

Every one of us is equal. Every one of us has worth. Every one of us matters. And when we respect the freedom of others -- no matter the color of their skin, or how they pray or who they are or who they love -- we are all more free. Your dignity depends on my dignity, and my dignity depends on yours. Imagine if everyone had that spirit in their hearts. Imagine if governments operated that way. Just imagine what the world could look like -- the future that we could bequeath these young people.

If you're walking down the right path and you're willing to keep walking, eventually you'll make progress.
