Eugene Robinson, Washington Post columnist: "I think we still don’t get how big of a deal this is. This man defined this young century for us and for the world. The impact that he had on the United States is just tremendous. Two wars, bankrupting the treasury, changed the bargain we make between freedom and security, and made us think whenever we see a gym bag lying in the corner: we don't think someone's just been absent-minded. We think it might blow up. And for him to be gone, I think, makes a huge difference."
