Not for one moment suggesting that some do not try to pull a fast one, on the photo in the link it is anyway not clear what the lettering says. Kyrgyz registration usualy standard on rear fuselage and under wing. On this photo it would appear if reg no is on top of one wing also.
Merely pointing out implications if UN and bleeding hearts reporters start singling out all-white Kyrgyz registered aircraft for special attention. If UN doesnt like - then it is simple to rid any potential for confusion by changing designator.
Me personally thinks this a case where the specialists in the region UN and AU etc. have run out of excuses for their inefficiency and failure in the region and need someone to blame.
I hold no brief for the Sudanese but believe world powers should get on with restoring peace in the region. A tale usualy has two sides. Next we will hear that Sudan also has the potential to produce weapons of mass destruction.
Many or most conflict situations in Africa develop and escelate out of control because of the intransigence, hypocracy, and inefficiency of the UN and AU, perhaps for many reasons, but just think how much money is to be made in the process by providing "peace-keeping" services once the fire is good and properly burning. Think of Iraq, and more recently the conflict in the DR Congo. The mess in the Congo was brought about by how it was decided by the major powers, the UN and AU to get rid of Mobutu. Similarly the situation in Iraq. The legacy and consequences of the regime change in the DRC and the method rests firmly on the shoulders of those powers who chose to do so, and sponsored and equiped the event. In Africa we all know who they were.
Some people and individuals make a lot of money in these processes, instead of just putting down their foot and chasing the offensive party/ies away. A simple matter considering the technology today. A classic and better example of perhaps the other extreme is the situation in Zimbabwe where "The World" is first going to allow most the Zim nation to starve or flee to SA, before they put their foot down, or are also waiting for a major full scale civil war to erupt.
When all is lost and these wonderful agencies have all failed due to ineptitude or whatever, - simple - blame your own ineptitude on one or two AN-26 possibly Kyrgyz registered planes causing all the chaos.
