Nobody made a greater mistake than he who did nothing because he could only do a little.

I can't say it better than one of Daniel Mendelsohn's travelling companions does toward the end of this powerful work of investigative empathy: "The Holocaust is so big, the scale of it is so gigantic, so enormous, that it becomes easy to think of it as something mechanical. Anonymous. But everything that happened, happened because someone made a decision. To pull a trigger, to flip a switch, to close a cattle car door, to hide, to betray."

Bush recounted his strategy for fighting terrorism, saying the United States continues to consider any country that harbors a terrorist to be as guilty as the terrorist being harbored. He was applauded when he discussed his doctrine of preemptive strikes -- attacking enemies abroad before they can attack U.S. soil.

An idea comes as close to something for nothing as you can get.
