Barack Obama: “I express concern for the wounded, many of whom are being treated in Israeli hospitals.”

Every president here today, as different as we are, has tried our best to uphold the values that John McCain and Mitt Romney believed in no less than I did.

While we are non-partisan, we are not value-neutral. We have a point of view.

I think when you understand the complexities of America and the contradictions of America, I don’t think it makes you love it less. I think it makes you love it more.
