My position on how to deal with Gbagbo and the military units who support him has been clear from the beginning so I have no problem with the UN or the French or anyone firing on Gbagbo's palace or the military bases... but by doing so after allowing the Northern forces to cross the buffer zone first gives the impression that their actions are in support of the assault from the North. I therefore state that both the UN and the French are complicit in any war crimes committed by the northern forces after their unopposed crossing of the buffer zone.
I read their actions as simple pragmatism. Opposing the northern forces would have been a finger in the dyke; firing on the positions of the soon to be defeated side who were needlessly prolonging the fighting seems to be both a humanitarian move and a smart one in this context. How often do you see all those things go hand-in-hand?
