On Day One is a social media site sponsored by the United Nations Foundation and the Better World Campaign that asks everyday people to offer their ideas about what the next president should do, figuratively "on day one." In preparation for this discussion, we solicited On Day One users for their ideas on how the next president should take on the threat of global terrorism and many people responded by suggesting that if the United States does more to alleviate poverty in the developing world the terrorist threat could be mitigated.

But is terrorism actually linked to poverty? Is it linked to other externalities, like grievances with American foreign policy, perceived humiliation, nationalist political objectives, radical ideology --- or all of the above? Which is most dominant? Which is most underestimated in current approaches to terrorism?
