It will never happen because the prosecution would logically include Bush, Cheney, Rumsfeld, Rice, and some legislators. I don't see a Republican administration prosecuting them because of loyalty, and I don't see a Democratic one doing that because I suspect Pelosi and Obama could be prosecuted as well (if new evidence comes to light). And without going after the very highest level offenders, you're throwing the CIA under the bus, and that won't end well.
Obama probably would not be part of the group but Pelosi and Dianne Feinstein would. Jay Rockefeller as well. These three very senior leaders in the Democratic party have sat on the Foreign Intelligence Committee during this period of torture and while supposedly not completely in-the-loop approved of what they did know of.
Obama is the president of the country blatantly, in the open, violating Geneva Conventions - Gitmo, drone strikes. Not that anybody, who matters, cares though.
