Unless we free ourselves from a dependence on these fossil fuels... we are condemning future generations to global catastrophe

We've come to be consumed by a 24-hour, slash-and-burn, negative ad, bickering, small-minded politics that doesn't move us forward. Sometimes one side is up and the other side is down. But there's no sense that they are coming together in a common-sense, practical, nonideological way to solve the problems that we face.

E.U. need to be nurtured and cultivated and protected and fought for because the achievements that we've seen on this continent, in contrast to a divided Europe of the previous century, are ones that remind us of how important it is that we work together.

America’s possibilities are limitless, for we possess all the qualities that this world without boundaries demands: youth and drive; diversity and openness; an endless capacity for risk and a gift for reinvention. My fellow Americans, we are made for this moment, and we will seize it - so long as we seize it together.

The opportunity will not remain open indefinitely.

Shooting in Orlando is a sobering reminder that attacks on any American, regardless of race, ethnicity, religion or sexual orientation, is an attack on all of us and on the fundamental values of equality and dignity that define us as a country. And no act of hate or terror will ever change who we are or the values that make us Americans.

I don't want my generals or my defense secretary or my national-security team to ever feel deploying weapons to kill people as routine or abstract, even if the targets are bad people.
