Appealing to tribe, appealing to fear, pitting one group against another, telling people that order and security will be restored if it weren’t for t… - Barack Obama

More and more, we all confront difficult questions about how to prevent the slaughter of civilians by their own government, or to stop a civil war whose violence and suffering can engulf an entire region. I believe that force can be justified on humanitarian grounds, as it was in the Balkans, or in other places that have been scarred by war. Inaction tears at our conscience and can lead to more costly intervention later. That's why all responsible nations must embrace the role that militaries with a clear mandate can play to keep the peace.

I was from everywhere and nowhere at once, a combination of ill-fitting parts, like a platypus or some imaginary beast, confined to a fragile habitat, unsure of where I belonged. And I sensed, without fully understanding why or how, that unless I could stitch my life together and situate myself along some firm axis, I might end up in some basic way living my life alone. I didn’t talk to anyone about this, certainly not my friends or family. I didn’t want to hurt their feelings or stand out more than I already did. But I did find refuge in books.

Because of the work of generations, because we’ve stood together in a great alliance, because people across this continent have forged a European Union dedicated to cooperation and peace, we have made historic progress toward the vision we share -- a Europe that is whole and free and at peace. And yet, as we gather here today, we know that this vision is threatened by Russia’s aggression against Ukraine. It is a brazen assault on the territorial integrity of Ukraine -- a sovereign and independent European nation. It challenges that most basic of principles of our international system -- that borders cannot be redrawn at the barrel of a gun; that nations have the right to determine their own future. It undermines an international order where the rights of peoples and nations are upheld and can’t simply be taken away by brute force.
