Roberts: The war on terror, invented by the George W. Bush/Dick Cheney regime, destroyed the US Constitution and the civil liberties that the Constitution embodies. The Bill of Rights has been eviscerated. The Obama regime has institutionalized the Bush/Cheney assault on American liberty. Today, no American has any rights if he or she is accused of "terrorist" activity. The Obama regime has expanded the vague definition of "terrorist activity" to include "domestic extremist," another undefined and vague category subject to the government's discretion. In short, a "terrorist" or a "domestic extremist" is anyone who dissents from a policy or a practice that the US government regards as necessary for its agenda of world hegemony.
