"The job of the president is not merely to inspire. It is first and foremost to inform -- to help people see the world as it is, not as they wish it to be -- and then to craft policies based on that understanding. Barack Obama is so confident of his rhetorical powers that he violates such self-restraint. In his speech, he casually mentioned "hard choices" but didn't say what they are; he offhandedly acknowledged that combatting climate change will be "long" but didn't say why. His make-believe assumptions sound good but will have a short shelf life."
