Five years ago today, in Gleneagles, Scotland, the leaders of the G8 nations made a dramatic promise to the people of Africa. Amidst a background of 200,000 marchers vowing to "make poverty history", the G8 promised to double current aid to Africa, reaching a total of $25 billion in five years.  Now that the timeline is up, and only $18 billion has been paid out, it has become clear that those earlier promises have been broken.
