We need change that builds, rather than destroys. That means controlling arms supplies as the Arms Trade Treaty already requires governments to do. It means offering a refuge to those fleeing violence and persecution, as the Refugee Convention has for decades prescribed. We must also develop a Global Compact on Migration, to protect migrants, so often as vulnerable as refugees, and to manage migration for the benefit of all. If the terrible events of 2016 are not to be repeated, the calls for change to make the world more secure and inclusive must be heard and acted on. Nadi's experience may seem a million miles away from ours but we share the same thread of laws and norms that are supposed to keep us safe. Ultimately we are all in this together.
