We are not going to keep the window open forever.

We didn't become the most prosperous country in the world just by rewarding greed and recklessness. We didn't come this far by letting the special interests run wild. We didn't do it just by gambling and chasing paper profits on Wall Street. We built this country by making things, by producing goods we could sell.

A lot of countries have advanced capabilities. And given the vulnerabilities of our infrastructure and our economies to digital platforms, we have to be careful in making sure that this doesn't become a lawless, low-level battlefield.

True leadership will not be measured by the ability to muzzle dissent, or to intimidate and harass political opponents at home. The people of the world want change. They will not long tolerate those who are on the wrong side of history.

We Americans are not an inherently more violent people than folks in other countries. We're not inherently more prone to mental health problems. The main difference that sets our nation apart is what makes us so susceptible to so many mass shootings is that we don't do enough, we don't take the basic commonsense actions to keep guns out of the hands of criminals and dangerous people. What's different in America is it's easy to get your hands on a gun.

I believe marriage is between a man and a woman. I am not in favor of gay marriage. But when you start playing around with constitutions, just to prohibit somebody who cares about another person, it just seems to me that's not what America's about. Usually, our constitutions expand liberties, they don't contract them.

We are committed to a world in which we keep America safe, but we recognize that our power doesn't just flow from our extraordinary military but also flows from the strength in our ideals and our principles and our values.
