Pongochap - Logic and indeed international law does not indicate in any way that the decision to attack Iraq was legal. It's all very well putting some old resolutions in the microwave for ten minutes and instantly making them new again but when you conduct 'spikes of activity' which were the biggest bombing raids since the end of GWI we were clearly in a position of going far beyond the terms of the no-fly' zones.
As for being held not responsible for the decisions of politicians - I should think there are a great number who would question this in relation to the briefings given by Sir Mike Jackson whilst the CM of the abuse soldiers was underway. There isn't a clear demarkation between the decision to go to war taken by politicians and how that war is conducted by the armed forces.
