Again..Can Africans Deal With Their Own Problems?

The Nigerian president is due to attend a meeting on Saturday of regional leaders, hosted by France, that is expected to discuss a joint approach to Boko Haram. Until now there has been little cooperation among Nigeria, Benin, Niger, Cameroon and Chad; members of the Islamist group move with relative freedom across the region’s porous borders. The United States, the European Union and Britain will also be represented, according to a statement from the Nigerian presidency.

Why is this being hosted by France? How is this France's business or problem? Does France invite Nigerian officials to deal with it's internal problems?

Why is the European Union, Britain and the United States being represented? How is this any of their business? Are any US nationals in the hands of Boko Haram? Are any EU nationals in the hands of Boko Haram? Are any British Nationals in the hands of Boko Haram? The answer is no to all three so why are they present? Do any of these states or organizations solicit representation from any African state when they have problems (other than to claim that the "international community" approves of us meddling in the internal affairs of today's enemy state)?
