Kim Jong-un presided over solemn memorials to mark the second anniversary of his father's death on Monday. One particular snapshot can provide us with insight into the leadership in the wake of the recent brutal purge of his uncle, Chang Song-thaek, explains North Korea leadership specialist Michael Madden.

It could be the picture of "All those not at risk of being shot this weekend stand still everyone else one step back."

I have a book - "The Commissar Vanishes" by (if I recall) David King. It documents how people were erased from photos in Stalin's time. Lots of non-Photoshop airbrushing used. Very interesting, and I expect similar history re-writing happens in N Korea.

There is plenty of airbrushing of history going on. Even here the Tories ....

I expect at least a country or two in Europe to collapse into revolution. Ireland will collapse but not sure if the public will rise up. Several east European countries will collapse, and Greece will probably become a military dictatorship again to restore order. Hungary looks very vulnerable as well. Though once the revolutions start watch the coalition abandon austerity just long enough to avoid problems here.
