Sean-Paul at the Agonist and Nathan at Argus are having an interesting exchange of speculation on the situation in Uzbekistan. Both Sean-Paul and Nathan’s posts are crammed full of links, excerpts and knowledgeable commentary.
Sean-Paul discusses the possibility of an al Qaida connection to the bombings here- L’Affaire d’Ouzbeq and here – L’affaire d’Ouzbeq, Part II. His analysis strikes me as correct, considering that everyone is working with a minimum of hard information and the situation is very volatile.
