Perceptive Dagblog readers know the difference between Obama, Romney and Bush:

Obama NYT today: .how President Obama’s thinking about what he once called “a war of necessity” began to radically change less than a year after he took up residency in the White House....The aide told Mr. Obama that he believed military leaders had agreed to the tight schedule to begin withdrawing those troops just 18 months later only because they thought they could persuade an inexperienced president to grant more time if they demanded it. “Well,” Mr. Obama responded that day, “I’m not going to give them more time.”...Mr. Obama concluded in his first year that the Bush-era dream of remaking Afghanistan was a fantasy...

Mitt Romney, Feb. 2012 : LAS VEGAS -- LAS VEGAS -- Republican presidential candidate Mitt Romney on Wednesday night blasted President Obama and his administration for “putting in jeopardy” the nation’s military mission by signaling it hopes to end its combat mission in Afghanistan by the middle of 2013.

Appearing at a campaign rally here shortly after landing in Nevada, Romney said Defense Secretary Leon E. Panetta’s statement Wednesday that U.S. forces would transition from a combat mission in Afghanistan next year “makes absolutely no sense.”....

George W. Bush, from May, 2003:  BBC - "We do not know the day of final victory, but we have seen the turning of the tide... Free nations will press on to victory,"

Bush Afghanistan strategy :  Gen. Douglas E. Lute, who had spent the last two years of the Bush administration trying to manage the many trade-offs necessary as the Iraq war consumed troop and intelligence resources needed in Afghanistan, arrived with a PowerPoint presentation.  The first slide that General Lute threw onto the screen caught the eye of Thomas E. Donilon, later President Obama’s national security adviser. “It said we do not have a strategy in Afghanistan that you can articulate or achieve,” Mr. Donilon recalled three years later. “We had been at war for eight years, and no one could explain the strategy.”

Aristotle and Plato didn’t agree on much, but they were united in identifying wonder as the origin of their profession. As Aristotle said, “It is owing to their wonder that men . . . first began to philosophise.” This idea appeals to scientists, who frequently enlist wonder as a goad to inquiry. “I think everyone in every culture has felt a sense of awe and wonder looking at the sky,” wrote Carl Sagan in 1985, locating in this response the stirrings of a Copernican desire to know who and where we are.

Yet that is not the only direction in which wonder may take us. To Thomas Carlyle, wonder sits at the beginning not of science, but of religion. That is the central tension in forging an alliance of wonder with science: will it make us curious, or induce us to prostrate ourselves in pitiful ignorance? We had better get to grips with this question before we too hastily appropriate wonder to sell science.  That is surely what is going on when pictures from the Hubble Space Telescope are (unconsciously?) cropped and coloured to recall the sublime iconography of Romantic landscape painting, or the Human Genome Project is wrapped in biblical rhetoric, or the Large Had­ron Collider’s proton-smashing is depicted as “replaying the moment of creation”. The point is not that such things are deceitful or improper, but that if we want to take that path, we should first consider the complex evolution of the relation between science and wonder.

Pretending that science is performed by people who have undergone a Baconian purification of the emotions only deepens the danger that it will seem alien and odd to outsiders, something carried out by people who do not think as they do. Daston believes that we have inherited a “view of intelligence as neatly detached from emotional, moral and aesthetic impulses, and a related and coeval view of scientific objectivity that brand[s] such impulses as contaminants”. It is easy to understand the historical origins of this attitude: the need to distinguish science from credulous “enthusiasm”, to develop an authoritative voice, to strip away the pretensions of the mystical Re­nais­sance magus who acquired knowledge through personal revelation. We no longer need these defences, however; worse, they become a defensive reflex that exposes scientists to the ­caricature of the emotionally constipated boffin, hiding within thickets of jargon.
