Iran will for sure have pledged to the international community that it will not develop a nuclear weapon, and now will be subject to an additional protocol, a more vigorous inspection and monitoring regime that lasts in perpetuity.

I'll be honest, there have been times when I've listened to the rhetoric in Europe where an easy equivalent somehow between the United States and Russia and between how our governments operate versus other governments operate, where those distinctions aren't made.

Letting the free market do whatever it wants. That's not been historically how we grow. We have to invest in education, in rebuilding broadband lines and roads and runways, and it's important that we bring back American manufacturing and regulations to prevent consumers from being cheated.

Our alliances and partnerships are not directed against any nation.

The men and women of America's homeland security apparatus do important work to protect us, and Republicans and Democrats in Congress should not be playing politics with that.

Everything we've done has been designed to make sure that we address that number one priority. That's what the sanctions regime was all about. That's how we were able to mobilize the international community, including some folks that we are not particularly close to, to abide by these sanctions. That's how these crippling sanctions came about, was because we [USA] were able to gain global consensus that Iran having a nuclear weapon would be a problem for everybody.

Part of what makes me most optimistic is if you look at the attitudes of young people. Across the board, young people are much more comfortable with respecting differences. They are much more comfortable with diversity.
