Just in addition, there's the burden on host countries, especially those surrounding conflict areas. For example, I think that 85% of Syrian refugees are still in the region, in surrounding countries like Lebanon, Turkey and Jordan, so the burden is on those host countries.
As Anna said, resettlement is one option, but it's not necessarily what people want to do. It's not necessarily the best thing to do to resettle all of these refugees, but to support the host countries so they will be able to support refugees and displaced peoples, and again, go through the local organizations, especially when it comes to internally displaced, because often the problem is with the government.
