StrategyPage has a long detailed post on that war, and on the multinational African forces that are fighting them. Things are improved partly because the new president is fighting some of the terrible corruption.
and then we have this:
:The UN revealed that there are now over 2.2 million refugees from Boko Haram violence. In addition several hundred thousand people in neighboring Chad, Niger and Cameroon have also been displaced by Boko Haram violence.
hmm...haven't heard much about these refugees, but I suspect if you look closer, a lot of those "Syrian" refugees will turn out to be fleeing Nigeria or Saharan terrorist groups. And of course these Saharan groups make money by smuggling drugs and refugees from Europe.
