I can think about what [Mahatma] Gandhi said or [Martin Luther] King said about violence begetting violence, and still be true to my job by asking myself the question whenever we're confronted with a situation where some may be arguing for military action: Will this actually result in America being safer, or the most lives being saved?
Barack ObamaI'm not talking about blind optimism, the kind of hope that just ignores the enormity of the tasks ahead or the road blocks that stand in our path. I'm not talking about the wishful idealism that allows us to just sit on the sidelines or shirk from a fight. I have always believed that hope is that stubborn thing inside us that insists, despite all the evidence to the contrary, that something better awaits us so long as we have the courage to keep reaching, to keep working, to keep fighting.
