But, rebutting Hayden, he said: "What makes the United States special and what makes you special is precisely the fact that we are willing to uphold our values and our ideals even when it's hard, not just when it's easy, even when we are afraid and under threat, not just when its expedient to do so."So yes, you've got a harder job and so do I, and that's OK. And over the long term, that is why I believe we will defeat our enemies, because we're on the better side of history."
