Nellie I am not sure I agree with you. I think it is a lot more to do with the frequency of terrorist events in a country and, sadly, Kenya has had a lot - as have many countries in Africa with local insurgencies as well as arab extremists. The shopping mall atrocity in Nairobi received just as much attention as the Paris events.
Thinking back to the recent troubles in Ireland. When the IRA & Protestant Loyalists started their terrorist campaign in Ulster in the late 1960s - 70s every event shocked us. I can still remember the shock and horror of the death of the first British soldier there, I can even remember his name, but as the campaign developed the space given to yet another death or deaths in Northern Ireland, whether military or civilian, either in this country or any other occupied less and less space in the media and certainly was ignored elsewhere. I too became inured to just accepting further deaths as they occurred. I cannot rememeber the name of the second soldier to die in Ulster, or the third, fourth........etc.
