I found this very interesting documentary by Adam Curtis, first aired on BBC in 2004. It analyzes and follows the two sides that seem to dictate the mood of politics of late, internationally and sometimes locally. They are the neo-conservatives and the radical Islamists. You will have to set aside some time to watch these 3 one-hour episodes, but it is well worth it.
