ERIC POSNER: “Many of us said during the days of the Bush administration that restrictions on civil liberties motivated by the conflict with Al Qaeda would be maintained during any subsequent administration, whether Democratic or Republican, as long as the terrorist threat remained. This prediction has been amply confirmed. . . . The persistence of policies across ideologically divided administrations is good evidence that those policies are now mainstream rather than partisan and ideological. Of course, many people will continue to disagree with them, just as many people continue to object to a standing army and a central bank; but these people are now officially on the fringes. There will also continue to be arguments about interrogation practices and the like, but a wide range of Bush administration policies—indefinite detention without charges, trials by military commission, the use of military force against suspected terrorists in foreign countries, secrecy privileges that undermine litigation against government officials responsible for terrorism policies, profiling on the basis of nationality, and much else—are now politically entrenched.”
