If you are at all interested in political extremism, go straight to the (relatively) new hub that is the Extremis Project. Short updates by country experts, lengthy pieces of in-depth analysis, a growing research database – they have it all. Hell, they even ran a sort of birthday special for the FN’s 40th anniversary.My only qualm is the sheer volume of their output: four posts this morning before 9 am. So I should stop reading now and go back to work.
