Of all the sins which a leader can be guilty, few are as egregious as the simple refusal to lead. Watching President Barack Obama's at first deafening silence and then weak and hyper-cautious words on Iran has been disappointing and painful. Our president must decide if he will serve as leader, or spectator, of the free world. This time no one is asking an American president to send in troops; no one is suggesting the deployment of laser-guided bombs. All it takes is a forthright statement from the leader of the free world: "The people of the United States support the people of Iran in their legitimate quest for democracy and freedom and will hold accountable any and all parties responsible for the bloodshed of nonviolent demonstrators."
