. >> 7.5 million are refugees inside mirria. more than half of the population has been forced out of their homes. now, their places have been taken over by groups that they fear they have nothing in common with. it may take a long time before it's safe for them to return. one estimate i herd by one of the people servicing the ill-faith mediation efforts was that there are 2,000 militia groups with a name. individual groups with 10 or more fighters. it's harder to end a war with multiple groups fighting each other on the ground than a smaller conflict. however, it's important that we do not give up hope. if we believe that this is only going to have full speed of costs, it will go badly. what we have to believe and argue is that this is a manmade disaster, it's not a tsunami. it's a manmade disaster, it can be ended. we have to start in 2015, and by local ceasefires, by funding the humanitarian work, negotiating access to the children, by giving school to refugee children so they get hope. >> great to talk to you, joining oslo. >
