There has long been a tension between those who describe themselves as realists or idealists — a tension that suggests a stark choice between the nar… - Barack Obama

We gather here in memory of 20 beautiful children and six remarkable adults. They lost their lives in a school that could have been any school in a quiet town full of good and decent people that could be any town in America. Here in Newtown, I come to offer the love and prayers of a nation. I am very mindful that mere words cannot match the depths of your sorrow, nor can they heal your wounded hearts. I can only hope it helps for you to know that you’re not alone in your grief, that our world, too, has been torn apart, that all across this land of ours, we have wept with you. We’ve pulled our children tight. And you must know that whatever measure of comfort we can provide, we will provide. Whatever portion of sadness that we can share with you to ease this heavy load, we will gladly bear it. Newtown, you are not alone.

But we are here today because we know we cannot be complacent. For history travels not only forwards; history can travel backwards, history can travel sideways. And securing the gains this country has made requires the vigilance of its citizens. Our rights, our freedoms -- they are not given. They must be won. They must be nurtured through struggle and discipline, and persistence and faith. And one concern I have sometimes during these moments, the celebration of the signing of the Civil Rights Act, the March on Washington -- from a distance, sometimes these commemorations seem inevitable, they seem easy. All the pain and difficulty and struggle and doubt -- all that is rubbed away. And we look at ourselves and we say, oh, things are just too different now; we couldn’t possibly do what was done then -- these giants, what they accomplished. And yet, they were men and women, too. It wasn’t easy then. It wasn’t certain then. Still, the story of America is a story of progress. However slow, however incomplete, however harshly challenged at each point on our journey, however flawed our leaders, however many times we have to take a quarter of a loaf or half a loaf -- the story of America is a story of progress. And that’s true because of men like President Lyndon Baines Johnson.

As Commander-in-Chief, I have no greater responsibility than the security of the American people. As a father to two young daughters who are the most precious part of my life, I know that we see ourselves with friends and coworkers at a holiday party like the one in San Bernardino. I know we see our kids in the faces of the young people killed in Paris. And I know that after so much war, many Americans are asking whether we are confronted by a cancer that has no immediate cure.
