George H.W. Bush: “Our challenges are enormous. But remember, this is America, and here, great things are possible.”

This means that people of every race, religion, ethnicity can be fully and equally American. It means that bigotry or white supremacy in any form is blasphemy against the American creed.

We are here today, together, to strengthen and reform U.N. peacekeeping because our common security demands it.

Strength is not empty rhetoric. It's not bluster. And in my experience, the strongest person usually isn't the loudest one in the room.

the greatest threat facing us is not ISIS but is global warming.
