“George Bush seized on the 9/11 attack to usher in radical new surveillance and detention powers in the PATRIOT ACT, spied for years on the communications of US citizens without the warrants required by law, and claimed the power to indefinitely imprison even US citizens without charges in military brigs.

His successor, Barack Obama, went further by claiming the power not merely to detain citizens without judicial review but to assassinate them(about which the New York Times said: “It is extremely rare, if not unprecedented, for an American to be approved for targeted killing”). He has waged an unprecedented war on whistleblowers, dusting off Wilson’s Espionage Act of 1917 to prosecute more then double the number of whistleblowers than all prior presidents combined. And he has draped his actions with at least as much secrecy, if not more so, than any president in US history.
“… It has become challenging to keep up with all the ways in which the president has not only embraced, but expanded and institutionalized, George W. Bush’s most radical policies.
Two significant shifts have happened during the first months of Obama’s second term. Firstly, the reality of the president’s true policies has finally penetrated mainstream discussion, spurred on by the Guantánamo hunger strikes, revelations about en mass domestic surveillance, prosecution of journalists and whistleblowers, as well as by the growing consciousness about the drone assassinations.

With an executive order in early 2009, Obama explicitly authorized the CIA to continue extraordinary renditions.  Like Bush, Obama has claimed that diplomatic assurances, along with oversight, will make sure that torture won’t be used – but this has not been the case.
…Obama has also explicitly authorized the CIA to continue “extraordinary renditions” to other countries, resulting in torture
…After expanding his own presidential authority by asserting the right to decide on terrorism suspects’ guilt without any legal process, and to detain individuals on suspicion of possible future crimes (see point 1.3), Obama took the expansion of executive power one step further: In January 2010, the Director of National Intelligence, Adm. Dennis Blair, testified before Congress that the Obama administration is reserving the right to include Americans on the assassination list, and kill them anywhere abroad at any time, without legal oversight.
… Obama has surpassed Bush and and Reagan in defense spending, with the largest combined budget for the military since World War II. … Obama has hiked the spending on, and use of, Special Operations forces, secretly deployed them to 75 countries, and extended de facto “secret wars” to Somalia and Yemen. Moreover, he started a full-fledged military campaign in Libya.
