In this miasma of forgotten wars, torture and the war on terror, there are no easy answers, especially in the face of a very real terrorism. But I can live my questions. As a humanitarian, I can act from a feeling of shared vulnerability with the victims of preventable suffering. I have a responsibility to bear witness publicly to the plight of those I seek to assist and to insist on independent humanitarian action and respect for international humanitarian law. As a citizen, I can assume my responsibility for the public world - the world of politics - not as a spectator, but as a participant who engages and shapes it. The larger force that can push back against the wrong use of power can be the force of a citizen's politics that openly debates the right use of power and the reasoned pursuit of justice. Catherine Lu, a political philosopher and my friend, has described justice as a boundary over which we must not go, a bond of common humanity between us, a balance among people of equal worth and dignity. I fight not for a utopian ideal, but each day I make a choice, against nihilism and towards justice.
