If you are interested in social networks, you’ll likely be familiar with the work of Valdis Krebs who modelled relationships between the 9/11 terror cells. He’s turned his attention to international relations and the results are available on his site.Whatever you think of his political alignments (Al Qaeda is directly linked to Hamas), it is impressive when you see it move around, and it neatly portrays some less obvious dilemmas and some more obvious relationships.
